Summary
Familial aggregation is significant in Progressive Supranuclear Palsy (PSP) and Corticobasal Syndrome (CBS), suggesting a genetic role. Further research into genetic factors influencing PSP and CBS is needed.
Area of Science:
- Neuroscience
- Genetics
- Neurology
Background:
- Familial aggregation studies are crucial for understanding the genetic basis of neurodegenerative diseases.
- Limited research exists on the familial aggregation of Progressive Supranuclear Palsy (PSP) and Corticobasal Syndrome (CBS).
Purpose of the Study:
- To determine the prevalence of a positive family history (FH) in a large cohort of patients diagnosed with PSP and CBS.
- To investigate the role of genetic background in the etiology of PSP and CBS.
Main Methods:
- A cohort of 230 patients with PSP or CBS and 110 controls were assessed.
- Clinical, neurological, neuropsychological evaluations, and brain imaging were performed.
- Standardized questionnaires collected data on familial aggregation.
Main Results:
- Positive family history was observed in 31.8% of PSP and 31.7% of CBS patients, significantly higher than controls (21.8%).
- PSP patients showed a higher FH for Parkinsonism (63.4%) compared to dementia (36.6%).
- FH was not correlated with age at disease onset in either PSP or CBS.
Conclusions:
- The findings support familial aggregation in PSP and CBS, highlighting the importance of genetic factors.
- Further investigation into genetic modulators and epistasis is warranted for PSP and CBS development.

01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:24Parkinson Disease l: Introduction
Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of which...
01:15Parkinson's Disease: Overview
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...
03:03Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
