Cognitive decline is a major non-motor symptom in Parkinson’s disease (PD), often linked to brain atrophy. This study examines the relationship between cortical atrophy and age groups in predicting cognitive decline in PD over five years. 188 PD patients from the COPPADIS cohort were stratified by age: young (30–55 years, N = 47), middle-aged (56–65 years, N = 59), and older adults (66–75 years, N = 82). Baseline cortical volume was assessed using T1-weighted MRI, and cognitive decline was evaluated using the annual rate of change of the Parkinson’s Disease-Cognitive Rating Scale (PD-CRS). Parametric or non-parametric tests were applied to evaluate group differences. Main analyses consist of several multiple regression analyses to examine associations between baseline brain atrophy and cognitive decline by age group. Older adults exhibited significantly greater cognitive decline in comparison to the younger age groups in the three compose scores of the PDCRS -Fronto-subcortical (H(2) = 41.08, p < 0.001), Posterior Cortical (H(2) = 22.03, p < 0.001), and Total(H(2) = 41.13, p < 0.001). Higher educational level has a significant positive effect on older adults, specifically for working memory performance, delayed verbal memory and the fronto-subcortical composed score. Multiple regression models underscored the predictive value of the bilateral hippocampus, bilateral medial orbitofrontal cortex, right precuneus, and right isthmus cingulate gyrus, together with being an older adult or having a higher education. MRI measures, age, and education predict cognitive decline in PD. Longitudinal assessments are essential for refining atrophy-cognition correlations and optimizing patient stratification.

The increase in unauthorized dissemination of erotic-sexual content, and the resulting forwarding chains, has emerged as a concerning manifestation of cyberviolence among adolescents that needs to be addressed. This research explored the factors associated with the persistence of involvement in, and repeated victimization through, non-consensual forwarding. A total of 2604 adolescents (53.4% female) aged 11–19 years (M = 14.89; SD = 2.04) participated. Two subsamples were identified: those who had repeatedly engaged in non-consensual forwarding (n = 213) and those who had frequently been the victim of non-consensual forwarding (n = 297). Sexism, gender, and cyberbullying proved to be the main relevant factors in the persistence of this form of cyberviolence. Specifically, both benevolent and hostile sexism predicted persistent engagement in non-consensual forwarding, although hostile sexism predicted it in boys, not girls. Cyberbullying predicted the repeated victimization of non-consensual forwarding. The co-occurrence with cyberbullying reinforces the notion that non-consensual forwarding may serve as a mechanism for victim harm. Gender and cyberbullying victimization also predicted victimization by non-consensual forwarding, but the results had very small effect sizes. These findings underline the high relevance of sexism and gender in understanding what drives adolescents to persist in non-consensual forwarding. The results are discussed in light of potential normalization processes that may underlie the repetition of these behaviors. Key elements for developing prevention programs to eradicate this type of cyberviolence among youth are identified.
Simultaneous Analysis of Early Components P1 and N1 and Phase and Non-Phase Alpha Activities Associated with Word Recall
(MDPI, 2025) Vázquez Marrufo, Manuel; Navarro Martos, Remedios; Narbona González, Natividad; Martín Clemente, Rubén; Universidad de Sevilla. Departamento de Teoría de la Señal y Comunicaciones; Universidad de Sevilla. Departamento de Psicología Experimental
The study of non-phase modulation of different frequencies in the human electroencephalography (EEG) is revealing new mechanisms involved in information processing. In particular, it has been described that the alpha band, through a desynchronization of its non-phase component, could represent a mechanism for sensory gain in visual stimulus processing. One key question to address is whether this activity can be modulated (increased) by the recall of a previously memorized stimulus. The objective of this study is to answer this question by recording EEG activity with 58 electrodes and applying time-frequency analysis techniques (Temporal Spectral Evolution and the Hilbert Transform) in a sample of 27 human participants during a word recall task. The results of the study showed an increase in alpha phase modulation for recalled words compared to not recalled words, which included modulation of the P1 component. Additionally, alpha non-phase modulation also increased for recalled words, suggesting that the enhanced P1 component response could, in fact, be an indirect result of the attenuation of background neural noise, as proposed by the sensory gain hypothesis.
Negotiating relationships within multispecies families: analysing dilemmas on humanisation of the bond
(Springer, 2025) López-Cepero Borrego, Javier; Español Nogueiro, Alicia; Universidad de Sevilla. Departamento de Personalidad, Evaluación y Tratamiento Psicológicos; Universidad de Sevilla. Departamento de Psicología Experimental
The literature indicates that companions are frequently considered part of our families. But, what does it mean? This article examines how the relationship between humans and nonhuman animals is defined within the family organization. We organized three online focus groups interviews, and the analysis was conducted using reflexive thematic analysis. The relationships with animals seemed to be based on four themes: (1) external limits (legal, moral, and biological) that frame the human-animal relationship; (2) participants’ perception of their role within the relationship (e.g. caregivers); (3) characteristics perceived in the animal that determine her inclusion as a member of the family; and (4) level of humanisation understood from a two-dimensional model: according to the similarity between species and the balance between the needs of humans and non-human animals. These findings provide new perspectives on multispecies families and highlight unresolved dilemmas in dominant social discourses.
Enseñanza remota de emergencia por COVID-19 en la Universidad Autónoma de la Ciudad de México
( Red de Investigadores Educativos Chihuahua AC, 2024) Rodríguez Ruiz, Sergio Guillermo; Manzano Arrondo, Vicente; Universidad de Sevilla. Departamento de Psicología Experimental
El confinamiento por COVID-19 obligó a las universidades en México a adoptar la enseñanza remota de emergencia (ERE) para dar continuidad a la educación. En este trabajo se reportan los resultados de la primera de tres fases de una investigación sobre prácticas docentes de profesores de la Universidad Autónoma de la Ciudad de México durante la ERE. Se llevaron a cabo entrevistas con tres profesores y tres estudiantes y sus respuestas fueron analizadas cualitativamente desde la perspectiva teórica del Marco de la comunidad de indagación para verificar la existencia de las distintas presencias que lo conforman: docente, social y cognitiva. Los resultados indican una tendencia más fuerte hacia la instrucción directa en comparación con la facilitación en la presencia docente, lo cual se ve reflejado, entre otros factores, por una carga mayor en el trabajo síncrono en contraposición con el asíncrono. La presencia social refleja pocas oportunidades para la socialización y cohesión grupal, así como una tendencia hacia el trabajo individual sobre el colaborativo. En la presencia cognitiva destaca la conveniencia de fortalecer las habilidades de indagación y la autorregulación de los estudiantes. Se concluye con algunas recomendaciones aplicables tanto a situaciones de ERE como a alternativas educativas multimodales
Predictive Modeling of Heart Rate from Respiratory Signals at Rest in Young Healthy Humans
(MDPI, 2024) Gómez González, Carlos María; Muñoz Burbano, Vanesa; Muñoz-Caracuel, Manuel; Universidad de Sevilla. Departamento de Psicología Experimental; Agencia Estatal de Investigación. España
Biological signals such as respiration (RSP) and heart rate (HR) are oscillatory and physiologically coupled, maintaining homeostasis through regulatory mechanisms. This report models the dynamic relationship between RSP and HR in 45 healthy volunteers at rest. Cross-correlation between RSP and HR was computed, along with regression analysis to predict HR from RSP and its first-order time derivative in continuous signals. A simulation model tested the possibility of replicating the RSP–HR relationship. Cross-correlation results showed a time lag in the sub-second range of these signals (849.21 ms ± SD 344.84). The possible modulation of HR by RSP was mediated by the RSP amplitude and its first-order time derivative (in 45 of 45 cases). A simulation of this process allowed us to replicate the physiological relationship between RSP and HR. These results provide support for understanding the dynamic interactions in cardiorespiratory coupling at rest, showing a short time lag between RSP and HR and a modulation of the HR signal by the first-order time derivative of the RSP. This dynamic would optionally be incorporated into dynamic models of resting cardiopulmonary coupling and suggests a mechanism for optimizing respiration in the alveolar system by promoting synchrony between the gases and hemoglobin in the alveolar pulmonary system.

Adoptees, a group of children consistently shown to be at higher risk of psychosocial difficulties, face particular challenges during adolescence. However, few studies address the well-being of adopted adolescents, and cross-cultural comparisons are rarely reported. The present study assessed the life satisfaction of internationally adopted and non-adopted adolescents living in four European countries. An overall sample of 776 adolescents completed self-report questionnaires. Descriptive analysis and logistic regression models were performed to investigate the association between adoption status and life satisfaction. Adoptees were found at higher risk for low life satisfaction across countries compared to their non-adopted peers (OR = 5.73, 95%CI 2.70-12.16). Friend support was a protective factor, while poor communication with parents was a risk factor for low life satisfaction in both groups. Our findings highlighted the importance of promoting family and social relationships to support the well-being of adopted and non-adopted adolescents in diverse European countries.
Addressing the sources of inter-subject variability in E-field parameters in anodal tDCS stimulation over motor cortical network
(IOP PUBLISHING LTD, 2024) Franco-Rosado, Pablo; Callejón Leblic, María Amparo; Reina Tosina, Luis Javier; Roa Romero, Laura María; Martín Rodríguez, Juan Francisco; Mir Rivera, Pablo; Universidad de Sevilla.

Objetive: . Although transcranial direct current stimulation constitutes a non-invasive neuromodulation technique with promising results in a great variety of applications, its clinical implementation is compromised by the high inter-subject variability reported. This study aims to analyze the inter-subject variability in electric fields (E-fields) over regions of the cortical motor network under two electrode montages: the classical C3Fp2 and an alternative P3F3, which confines more the E-field over this region. Approach. Computational models of the head of 98 healthy subjects were developed to simulate the E-field under both montages. E-field parameters such as magnitude, focality and orientation were calculated over three regions of interest (ROI): M1S1, supplementary motor area (SMA) and preSMA. The role of anatomical characteristics as a source of inter-subject variability on E-field parameters and individualized stimulation intensity were addressed using linear mixed-effect models.Main results. P3F3 showed a more confined E-field distribution over M1S1 than C3Fp2; the latter elicited higher E-fields over supplementary motor areas. Both montages showed high inter-subject variability, especially for the normal component over C3Fp2. Skin, bone and CSF ROI volumes showed a negative association with E-field magnitude irrespective of montage. Grey matter volume and montage were the main sources of variability for focality. The curvature of gyri was found to be significantly associated with the variability of normal E-fields.Significance. Computational modeling proves useful in the assessment of E-field variability. Our simulations predict significant differences in E-field magnitude and focality for C3Fp2 and P3F3. However, anatomical characteristics were also found to be significant sources of E-field variability irrespective of electrode montage. The normal E-field component better captured the individual variability and low rate of responder subjects observed in experimental studies.
A systematic review of the use of blogs and vlogs as self-expressors for people with serious and common mental illness
(Springer, 2025) Muñoz-del-Pino, Iris María; Matías García, José Antonio; Saavedra Macías, Francisco Javier; Universidad de Sevilla. Departamento de Psicología Experimental
The use of blogs and vlogs by people with serious mental illness (SMI) and common mental illness (CMI) has attracted increasing academic interest due to the development of online illness narratives. This systematic review aims to explore the use of blogs and vlogs, identifying their narratives and characteristics, perceived benefits and adverse effects associated os their use. This would allow us to know the influence of this type of media on authors’ personal recovery. Following PRISMA guidelines, an exhaustive search of four databases was conducted, using terms such as ‘blog’, ‘vlog’ and ‘serious mental illness’ among the most relevant. The selected articles were empirical studies, written in English, published in peer-reviewed journals from 2014 to 2024 and explored the use of blogs and vlogs by people with SMI and CMI. Eighteen studies met the inclusion criteria. Self-expression narratives on these platforms tend to be first-person and address issues such as stigma, barriers to treatment and self-management of symptoms. Key benefits include the creation of support networks, reduction of social isolation and individual empowerment, all of which are intrinsically related to personal recovery. However, risks were also identified, such as the possibility of employment discrimination and emotional vulnerability to negative comments. This review highlights the need for future research that explores cross-cultural experiences and provides a sound basis for the design of interventions that promote the positive use of blogs and vlogs in mental health recovery.

Maladaptive cortical plasticity has been described in individuals with heroin and methamphetamine addiction and may mediate other substance abuse disorders. It is unknown whether cannabis dependence in humans alters the capacity for induction of cortical plasticity. The aim of this study was to non-invasively investigate cortical plasticity with transcranial magnetic stimulation in young adults who meet DSM-5 criteria for cannabis use disorder (CUD). Thirty men (ages 20– 30) who used cannabis daily over the previous 6 months (15 diagnosed of CUD) and 15 demographically matched non-users were enrolled in this study. All participants underwent two sessions of theta burst stimulation (TBS) in which either continuous TBS (cTBS; 600 pulses, 80% active motor threshold) or intermittent TBS (iTBS; 2-s train of cTBS repeated every 10 s for a total of 190 s, 600 pulses) was applied over the primary motor cortex. The effects of these protocols were assessed by analysing the contralateral motor evoked potentials (MEPs). The relationships between cortical plasticity and problematic cannabis use, degree of dependence, and nicotine addiction were also investigated. Significant MEP inhibition after cTBS was observed in both cannabis users without CUD and non-users, while this inhibition was not seen in cannabis users with CUD. Strikingly, less motor cortical plasticity was observed in subjects with severe problematic cannabis use. No significant differences between users and non-users were found in the iTBS-induced cortical plasticity measures. Our study provides the first evidence of maladaptive cortical plasticity associated with cannabis use disorder and problematic cannabis use in humans.
Short-afferent inhibition and cognitive impairment in Parkinson's disease: A quantitative review and challenges

Traditionally, Parkinson’s disease (PD) has been considered a single neurotransmitter (dopaminergic) disease. However, research over the past 20 years has shed light on the involvement of multiple neurotransmission systems, in particular, the cholinergic system. Research has mainly focused on the role of this system in the pathophysiology of PD and its implications in the development of motor and non-motor disorders. Short-latency sensory afferent inhibition (SAI), investigates sensori-motor integration, and has emerged as a putative neurophysiological marker of cholinergic function in the human brain. In this quantitative review, a moderate-to-severe reduction in SAI was observed in PD patients. Furthermore, through moderator analysis, the impairment of SAI was shown to be associated with disease duration and therapeutic state. Patients under dopaminergic agents (“on” state) displayed worse SAI than those after dopaminergic agent withdrawal (“off”). We further assess the potential value of SAI as a marker of cognitive impairment in PD, and its association with four specific cognitive domains. This analysis revealed that patients with cognitive impairment displayed significantly lower levels of SAI than those without cognitive impairment. To conclude, a set of challenges to be addressed before SAI can be validated as a useful clinical tool in PD are presented.
Mujeres, ciencia y psicología: el ininterrumpido debate sobre el determinismo biológico
(Colegio Oficial de Psicología de Andalucía Occidental, Universidad de Cádiz, Universidad de Córdoba, Universidad de Huelva, Universidad de Sevilla, 2025) Sánchez González, Natividad; Universidad de Sevilla. Departamento de Psicología Experimental
Aunque la psicología de género no fue reconocida como área de especialización hasta mediados del siglo XX, la construcción psicológica de la feminidad tiene un largo pasado que se remonta a la filosofía clásica. Este trabajo se centrará en considerar históricamente el papel que el determinismo biológico ha jugado en la conformación del espacio disciplinar de la psicología de género. Analizaré particularmente la contribución de la teoría de la evolución y de sus extensiones sociales y psicológicas que, usadas como argumento de autoridad científica, legitimaron usos sociales y sirvieron de barrera de contención ante las demandas feministas de la época. Se considerará la influencia de factores ajenos a lo científico en la determinación de sus modos de pensamiento, sus construcciones teóricas y sus prácticas. Examinaré, las reacciones al determinismo biológico, principalmente desde la psicología, que defendieron el origen social y cultural de las diferencias entre los sexos. Para concluir sostendré que el determinismo biológico todavía vigente especialmente en el campo de las neurociencias se basa en las mismas suposiciones que tiempo atrás y argumentando que el trabajo histórico puede ayudarnos a comprender mejor las dinámicas y las relaciones de poder actuales dentro de este dominio epistémico.
Sesgos de género: un análisis de los factores que contribuyen a la desigualdad en la investigación psicológica
(Colegio Oficial de Psicología de Andalucía Occidental, Universidad de Cádiz, Universidad de Córdoba, Universidad de Huelva, Universidad de Sevilla, 2025) García Jiménez, María; Trigo Sánchez, María Eva; Universidad de Sevilla. Departamento de Psicología Experimental
Los sesgos de género que se producen en la investigación, si bien no siempre ocurren de forma consciente, contribuyen a mantener o acentuar las desigualdades entre hombres y mujeres. Como ocurre en otras ciencias, la psicología tampoco es ajena a este tipo de errores sistemáticos. El objetivo de este trabajo es identificar en qué situaciones son susceptibles de aparecer este tipo de sesgos y de qué forma se cometen en la investigación en psicología. Para ello, se analiza el impacto que tienen dichos sesgos a lo largo de las distintas etapas que componen el proceso de una investigación psicológica, desde la formación del grupo de trabajo que realizará la investigación hasta el momento de su publicación. En cada etapa de investigación se proponen estrategias para evitar investigaciones potencialmente sesgadas sobre la base de ejemplos que sirven para ilustrar algunos sesgos de género que se han cometido en trabajos empíricos previos. Se concluye sobre la relevancia de la formación en y con perspectiva de género en los planes de estudio en psicología para favorecer una ciencia psicológica precisa y una práctica profesional de calidad.
Pensar despacio sobre las mujeres que sufren violencia machista
(Colegio Oficial de Psicología de Andalucía Occidental, Universidad de Cádiz, Universidad de Córdoba, Universidad de Huelva, Universidad de Sevilla, 2025) Cala Carrillo, María Jesús; García Jiménez, María; Universidad de Sevilla. Departamento de Psicología Experimental
Durante la intervención con mujeres que han sufrido algún tipo de violencia machista, diferentes profesionales tomarán decisiones (e.g., creerlas o no) y harán atribuciones a su comportamiento (por ejemplo, responsabilizarlas de la violencia que sufren) mediadas por creencias previas estereotipadas sobre las víctimas, en ocasiones erróneas. Esta actuación inadecuada de quienes supuestamente deben ayudarlas y/o protegerlas, puede llevar a una victimización secundaria. El objetivo de este trabajo es ilustrar la relevancia de dicho pensamiento estereotipado señalando el papel que juega en la toma de decisiones. Partiendo de la distinción del pensamiento rápido y pensamiento lento de Daniel Kahneman, nos centramos en el primero y en su relación con los estereotipos de género y el papel que juegan en nuestras atribuciones y toma de decisiones. Seguidamente profundizaremos en tres creencias estereotipadas sobre las mujeres que sufren violencia para contrastarlas con lo que desde la investigación psicológica se sabe sobre ellas y sus experiencias: (1) creer que las mujeres víctimas son pasivas, no se resisten a la violencia, (2) creer que mienten cuando la denuncia no se interpone inmediatamente después de un episodio de violencia y (3) creer que mienten si su relato presenta inconsistencias. El trabajo concluye resaltando la importancia de tomar conciencia sobre dichas creencias y la necesidad de reemplazarlas por un pensamiento basado en la evidencia científica para disminuir así el riesgo de victimización secundaria. Esto requiere, necesariamente, de una formación y especialización profesional con base en la investigación psicológica.
Equidad de los test psicológicos desde una perspectiva de género: análisis de buenas prácticas en psicometría
(Colegio Oficial de Psicología de Andalucía Occidental, Universidad de Cádiz, Universidad de Córdoba, Universidad de Huelva, Universidad de Sevilla, 2025) Rivera de los Santos, Francisco José; Universidad de Sevilla. Departamento de Psicología Experimental
Los test psicológicos son herramientas clave en la evaluación de características cognitivas, sociales, emocionales y comportamentales. En el estudio de las propiedades psicométricas de dichos test se abordan de forma frecuente las evidencias de fiabilidad y validez, pero el análisis de la equidad, específicamente desde una perspectiva de género, sigue siendo un reto. Este artículo analiza las prácticas habituales en el abordaje de género en la construcción y análisis de estos instrumentos. A través de una revisión sistemática de 20 estudios publicados en el año 2023 en revistas especializadas del campo de la evaluación psicológica, se identifican buenas prácticas psicométricas para abordar la equidad de género. Los resultados muestran que, aunque algunos estudios incluyen análisis de funcionamiento diferencial de ítems (Differential Item Functioning, DIF) y pruebas de invarianza factorial, son pocos los que desglosan resultados por género o implementan medidas adecuadas y sistemáticas para abordar la equidad. El artículo propone una serie de recomendaciones para garantizar la equidad de género en la psicometría, destacando la importancia de integrar análisis diferenciados por género en todas las etapas del desarrollo y validación de los test psicológicos. Se concluye que una mayor atención a la equidad de género es esencial para evitar sesgos que distorsionen los resulta-dos y asegurar evaluaciones justas.
Laziness and competence: The discursive social construction of resilient learner identity
(PERGAMON-ELSEVIER SCIENCE LTD, 2025) Matías García, José Antonio; Cubero Pérez, Mercedes; Cubero Pérez, Rosario; Universidad de Sevilla. Departamento de Psicología Experimental; Universidad de Sevilla. Departamento de Psicología Evolutiva y de la Educación
Students from marginalised and impoverished areas face significant challenges that increase the likelihood of school dropout and social exclusion. However, some students exhibit a resilient trajectory, completing compulsory studies and pursuing education beyond that level. To do so, these students must construct a learner identity that is coherent with school continuation while navigating the difficulties present in their context. The objective of this article is to examine the social construction of the learner identity of students who present such a resilient trajectory. The sample consisted of four focus groups of post-compulsory education students from Spain. Their discourse was studied qualitatively through an I-position and voices analysis, examining their view of themselves, the voices of their parents, teachers, peers and people from their neighbourhood, and the student’s view of others. The results indicated that the students developed a ‘lazy but capable’ view of themselves, in line with the social discourses present in the voices of their parents, teachers, and peers. Their voices served as resources for identity construction in interaction, which allowed the students’ confrontation and navigation of several risk factors from their context. Additionally, the view of others (i.e. enriched neighbourhoods) impacted the students’ construction of themselves. Lastly, the transformation of negative past self-views as positive ones in the present was frequent. The implications for psychosocial interventions in vulnerable neighbourhoods are discussed.
Psicología de las Mujeres y de Género. Introducción al Monográfico
(Colegio Oficial de Psicología de Andalucía Occidental, Universidad de Cádiz, Universidad de Córdoba, Universidad de Huelva, Universidad de Sevilla, 2025) García Jiménez, María; Cala Carrillo, María Jesús; Barberá Heredia, Ester; Universidad de Sevilla. Departamento de Psicología Experimental
La publicación en 2004 del libro Psicología y Género, editado por Ester Barberá-Heredia e Isabel Martínez-Benlloch, y su vertebración en torno a la necesidad de incorporar el género como categoría de análisis en cualquier investigación psicológica ha tenido gran impacto en España especialmente en la psicología académica feminista. El legado de esta obra ha continuado a través de sucesivos encuentros realizados en 2018, 2020 y, especialmente, en 2023, donde varias colegas, algunas coautoras de aquella obra, compartieron saberes y ejemplos de buenas prácticas con un propósito similar a la misma. Este monográfico es el resultado de aquellos encuentros y, tras el vigésimo aniversario de la obra original, tiene por objetivo revisitar algunos debates y aspectos de interés en la psicología de género, exponiendo logros alcanzados y desafíos pendientes. Se plantea también desde un enfoque de género tanto en la investigación como en el desempeño profesional que ayude a superar visiones sesgadas que suelen perjudicar especialmente a las mujeres. Sigue siendo necesaria la investigación y la transferencia de conocimientos para supe-rar estos sesgos hacia una psicología más capacitada para abordar los desafíos de las situaciones de desigualdad que aún persisten en nuestra sociedad, y a ello es a lo que se pretende contribuir con las once aportaciones que incluye este número.

Parkinson’s disease (PD) patients who present with tremor and maintain a predominance of tremor have a better prognosis. Similarly, PD patients with high levels of uric acid (UA), a natural neuroprotectant, have also a better disease course. Our aim was to investigate whether PD motor subtypes differ in their levels of UA, and if these differences correlate with the degree of dopamine transporter (DAT) availability. We included 75 PD patients from whom we collected information about their motor symptoms, DAT imaging and UA concentration levels. Based on the predominance of their motor symptoms, patients were classified into postural instability and gait disorder (PIGD, n = 36), intermediate (I, n = 22), and tremor-dominant (TD, n = 17) subtypes. The levels of UA and striatal DAT were compared across subtypes and the correlation between these two measures was also explored. We found that PIGD patients had lower levels of UA (3.7 vs 4.5 vs 5.3 mg/dL; P<0.001) and striatal DAT than patients with an intermediate or TD phenotype. Furthermore, UA levels significantly correlated with the levels of striatal DAT. We also observed that some PIGD (25%) and I (45%) patients had a predominance of tremor at disease onset. We speculate that UA might be involved in the maintenance of the less damaging TD phenotype and thus also in the conversion from TD to PIGD. Low levels of this natural antioxidant could lead to a major neuronal damage and therefore influence the conversion to a more severe motor phenotype.
