ABSTRACT
OBJECTIVE: This study aims to explore the relationship between the burden of cerebral small vessel disease (CSVD) on imaging and cognitive impairment (CI) in patients with chronic obstructive pulmonary disease (COPD). METHODS: The study included 118 COPD patients admitted to Changxing People's Hospital between July 2020 and July 2023. All patients received a 1.5T MRI of the brain and pulmonary function tests. A cognitive function assessment was conducted via the Montreal Cognitive Assessment (MoCA) scale, and patients were divided into two groups. The relationship between the MoCA and CSVD burden score was analyzed by Pearson correlation, and to identify risk factors, multiple logistic regression analysis was performed. RESULTS: The study showed a negative correlation between the MoCA and CSVD burden score in COPD patients (r=-0.479, P<0.001). Multiple logistic regression analysis found that age (OR=2.264, 95% CI: 1.426-3.596, P<0.001), COPD grade (OR=3.139, 95% CI: 2.012-4.898, P<0.001), as well as CSVD burden score (OR=5.336, 95% CI: 1.191-23.900, P<0.001) were the independent risk factors for CI in COPD patients (P<0.05). CONCLUSION: When screening for cognitive impairment in COPD patients, the CSVD burden score can be used in conjunction with cognitive assessment scales to make judgments.
ABSTRACT
A doença de Huntington (DH) é uma desordem neurodegenerativa, que cursa com distúrbios motores, cognitivos e comportamentais que contribuem para o comprometimento da funcionalidade. Este estudo investigou o grau de funcionalidade e acometimento de indivíduos portadores da DH, com o Índice de Barthel Modificado (IBM) e por meio do Disease Burden Score (DBS). As variáveis analisadas de cada indivíduo foram: a idade atual, o gênero, a idade de início da doença e o número das repetições CAG (gene HTT). Seis indivíduos foram avaliados, três do sexo masculino 63,6 anos (±10,9) e três do sexo feminino 58,3 anos (±14,2) com o diagnóstico genético positivo para DH provenientes do município de Ervália/MG. O sexo feminino apresentou a idade de início menor comparado ao sexo masculino, com média de 38,3 anos (±8,9) e 46,6 anos (±7,6), respectivamente. O valor médio do número de repetições CAG no sexo feminino foi de 46,3 (±4,1) e no sexo masculino, 42,33 (±1,5). O grau de desempenho funcional determinado pelo IBM foi de 9,3 (±1,1) para o sexo feminino, com dependência total, e para o sexo masculino, 36 (±4,3), com dependência severa. O valor médio obtido pelo DBS no sexo feminino foi de 596,8 (±101,9), com maior grau de acometimento da doença comparado ao sexo masculino com 425,1 (±39,2). O grupo de mulheres com DH apresentou início dos sintomas mais cedo com maior número de expansões CAG quando comparado ao grupo masculino. Todos os pacientes apresentaram dependência total em relação à execução das atividades de vida diária. Sugere-se que pesquisas futuras sejam realizadas com maior número de indivíduos afetados pela DH para que os resultados observados sejam confirmados.
Huntington's disease (HD) is a neurodegenerative disorder, presenting with motor, cognitive and behavioral impairments that contribute to the decrease of the functional performance. This study investigated the degree of functionality and impairment of individuals with HD using the Modified Barthel Index (MBI) and the Disease Burden Score (DBS). The following variables were investigated : the age of onset, the gender, the current age and the number of CAG (HTT gene) repeats. Six HD patients from the municipality of Ervália-MG, three males 63.6 years old (±10.9) and three females 58.3 years old (±14.2), who had a positive genetic diagnosis for HD, were investigated. The female group had the lowest age of onset with an average of 38.3 years (±8.9), compared to the male group, with 46.6 years (±7.6). The mean of the number of CAG repeats in the female gender was 46.3 (±4.1) and in the male, 42.33 (±1.5). The degree of functional performance assessed by IBM was 9.3 (±1.1) for the female group, with total dependence, and for the male group, 36 (±4.3), with severe dependence. The mean of DBS value in the female group was 596.8 (±101.9) with a higher degree of disease involvement compared to the male group 425.1 (±39.2). The group of women with HD showed earlier onset of symptoms with a greater number of CAG repeats when compared to the male group. All patients presented total dependence on daily living activities. We strongly suggest further research involving a larger group of individuals affected by HD for statistical validation.

In Huntington's disease (HD), the presence of neurodegeneration in brain regions other than the striatum has been recently gaining attention. The amygdala is one such area, which has been investigated in only eight structural magnetic resonance imaging studies to date, but with inconsistent findings. This is the largest MRI study to date examining manually traced amygdala volumes in HD participants and the relationship of amygdala volumes to clinical measures of HD. Our study included 35 healthy control participants, and groups of 35 pre-symptomatic, and 36 symptomatic HD participants. When comparing the pre-symptomatic and symptomatic HD groups together against the control group, amygdala volumes were significantly lower in HD than controls and in symptomatic HD than pre-symptomatic HD. When examining relationships between amygdala volumes and clinical measures of HD, significantly smaller amygdala volumes were associated with worse motor and cognitive signs. For pre-symptomatic HD participants who were close to disease onset, smaller amygdala volumes were also associated with higher levels of anxiety symptoms. These findings suggest that the amygdala is affected in pre-symptomatic and symptomatic HD, and that the amygdala is related to the clinical profile of HD before onset of motor symptoms.
