Introduction: Since the declaration of coronavirus disease 2019 (COVID-19) as a pandemic, patients with dementia, were specifically vulnerable to the negative impact of the outbreak. Objective: To examine the association between lockdown amid COVID-19 pandemic and the rate of cognitive decline among patients with dementia and mild cognitive impairment (MCI). Methods: We conducted a cross-sectional observational study on patients with dementia and MCI who attended the outpatient clinic at Ibn Sina Hospital, the main tertiary neurology center in Kuwait, during the month of September 2020. The rate of cognitive decline, estimated by MMSE scores, was compared between the period prior to, and during lockdown. Results: We evaluated 36 consecutive patients with cognitive impairment (23 females [63.9%], mean age 71 ± 10.8 years, mean disease duration 34.6 ± 29 months). Eleven patients (30.6%) progressed to a more severe stage during the study period; 1 MCI (2.8%) converted to mild dementia, 6 (16.6%) mild to moderate, and 4 (11.1%) moderate to severe dementia. Monthly decline of MMSE scores before lockdown was 0.2 ± 0.1 points, while it was 0.53 ± 0.3 points during lockdown, which was statistically significant ( p = .001). The most affected cognitive domain was the memory with a mean decline of 1.5 ± 0.8 points. Conclusions: This study provides “real-world” data suggesting rapid cognitive decline in patients with dementia during the lockdown period. Healthcare systems should pay more attention to this vulnerable group, to help them maintain their mental, physical and social well-being during this crisis.
Background: Pituitary tumor apoplexy (PA) is an emergency condition caused by hemorrhage or infarction of the preexisting adenoma. Many factors are currently well-known to predispose to PA. However, during the period of coronavirus disease 2019 (COVID-19) pandemic, case reports of PA associated with COVID-19 infection have been sequentially published. To the best of our knowledge, four cases have been reported so far in the English literature. We herein report the fifth case of this association and review the pertinent literature. Case Description: A 55-year-old male patient with confirmed COVID-19 infection presented by progressive decrease in visual acuity and oculomotor nerve palsy. His medical history is notable for diabetes mellitus, hypertension, and pituitary macroadenoma resection 11 years ago. He was on hormonal replacement therapy for panhypopituitarism that complicated the surgery. Previous magnetic resonance (MR) imaging studies were consistent with enlarging residual pituitary adenoma. During the current hospitalization, computed tomography revealed hyperdensity of the sellar and suprasellar areas. MR imaging revealed PA in a recurrent large adenoma. Endoscopic endonasal transsphenoidal resection was uneventfully undertaken with near total excision of the adenoma and partial improvement of visual loss and oculomotor palsy. Histopathological examination demonstrated classic features of PA. However, his chest condition progressed and he had to be transferred to COVID-19 intensive care unit in the referring hospital where he was intubated and put on mechanical ventilation. One week later, the patient unfortunately passed away due to complications of severe COVID-19 pneumonia. Conclusion: We report the fifth case of PA associated with COVID-19 infection. Based on our patient’s clinical findings, review of the other reported cases, as well as the available literature, we put forth a multitude of pathophysiological mechanisms induced by COVID-19 that can possibly lead to the development of PA. In our opinion, the association between both conditions is not just a mere coincidence. Although the histopathological features of PA associated with COVID-19 are similar to PA induced by other etiologies, future research may disclose unique pathological fingerprints of COVID-19 virus that explains its capability of inducing PA.
Background: Ethnic variations have been described in medical conditions, such as hypertension, diabetes, and multiple sclerosis. Whether ethnicity plays a role in Parkinson's disease (PD), particularly with regard to non-motor symptoms (NMS), remains unclear. Existing literature is diverse, controversial, and inadequately documented. This review aims to analyse and report the currently available literature on NMS, specifically in Asian PD patients. Summary: We conducted a literature review using PubMed, searching for articles and currently available publications that reference and assess NMS in PD patients living in Asia using the validated NMS Questionnaire (NMS Quest) and NMS Scale (NMSS). In total, 24 articles were included: 12 using the NMS Quest and 12 using the NMSS. Symptoms of constipation, memory impairment, and nocturia were the most frequently self-reported symptoms (NMS Quest) in selected Asian populations, while symptoms within the domains sleep/fatigue, attention/memory, and mood/apathy were most prevalent when applying the health-professional completed NMSS. Key Messages: NMS are generally prevalent and highly burdensome within selected Asian PD populations living in countries included in this review. Our review suggests that NMS-driven phenotypic heterogeneity is present in Asian patients, and compared to Western PD populations there might be variations in assessed NMS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
