Study Notes
Neurodegenerative Diseases Overview
- Chronic neurological disorders primarily affecting humans.
- Characterized by progressive loss of function, structure, and number of neural cells.
- Leads to brain atrophy and severe cognitive deficits.
Mechanisms of Neurodegeneration
- Underlying mechanisms remain largely unclear and not fully understood.
- Often linked with abnormal protein synthesis.
- Accumulation of pathological proteins, such as β-amyloid or α-synuclein, is common.
- Pathological proteins may accumulate either inside neural cells or within the brain parenchyma, contributing to neurodegeneration.
