Background: Movement disorders are chronic diseases with an increasing prevalence in old age. Because these disorders pose a major challenge to patients, families, and health care systems, there is a need for reliable data about the future number of affected people.
Patients And Methods: We searched the literature to identify epidemiological studies to obtain age-specific prevalence data of movement disorders. We combined the age-specific prevalence data with population projections for Europe, the United States, and Canada.
Results: Movement disorders will increase considerably between 2010 and 2050. The highest increase will be for dementia with Lewy bodies. In several countries, we project a near doubling of patients with PD.
Conclusions: There will be a strong increase in the number of people affected by most movement disorders between 2010 and 2050. This increase will mostly depend on the future aging of populations in terms of their age structure and future life expectancy.

Duchenne Muscular Dystrophy (DMD) progressively leads to loss of limb function due to muscle weakness. The incurable nature of the disease shifts the focus to improving quality of life, including assistive supports to improve arm function. Over time, the passive joint impedance (Jimp) of people with DMD increases.

This study investigates the role of flavonoid Icaritin (ICT) in estrogen-deficient ovariectomized (OVX) female mice by activating the Estrogen receptor (ER)/ Phosphatidylinositol 3-kinase (PI3K)/Protein kinase B (Akt) signaling pathway, potentially delaying Parkinson's disease (PD) progression post-castration. Seventy-five 8-week-old C57BL/6J female mice underwent ovariectomy, followed by MPTP (20 mg/kg) injection for 7 days. ICT (20 mg/kg) was administered for 14 days, and motor function was assessed using various behavioral tests.

Traumatic brain injury (TBI) is identified as a risk factor for Parkinson's disease (PD), which is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN). However, the precise mechanism by which chronic TBI initiates PD pathogenesis is not yet fully understood. In our present study, we assessed the chronic progression and pathogenesis of PD-like behavior at different intervals in TBI mice.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by a repeat of the cytosine-adenine-guanine trinucleotide (CAG) in the huntingtin gene (HTT). This results in the translation of a mutant huntingtin (mHTT) protein with an abnormally long polyglutamine (polyQ) repeat. The pathology of HD leads to neuronal cell loss, motor abnormalities, and dementia.

Background And Objectives: Huge clinical and research gaps exist concerning the epidemiology, natural history, availability, and accessibility of care for sleep disorders in sub-Saharan Africa (SSA). This study aimed to profile the characteristics of patients referred for polysomnography and the frequencies of sleep disorders encountered at the new sleep laboratory in Dar es Salaam, Tanzania.
Materials And Methods: This retrospective hospital-based descriptive observational study was conducted at the Aga Khan Hospital Dar es Salaam.
