Alzheimer’s & Parkinson’s Disease
Alzheimer’s disease (AD) and Parkinson’s disease (PD) are two of the most common neurodegenerative disorders, affecting millions worldwide. Both conditions involve progressive damage to brain cells, leading to cognitive and motor impairments. While they share some similarities, such as abnormal protein accumulation and neuroinflammation, they differ in their primary symptoms and affected brain regions. Alzheimer’s disease is a progressive neurodegenerative disorder primarily affecting memory, thinking, and behavior. It is the leading cause of dementia, accounting for 60-80% of cases. The disease is characterized by the accumulation of beta-amyloid plaques and tau tangles, which disrupt neural communication and lead to neuronal death.The early symptoms of AD include mild memory loss, confusion, and difficulty finding words. As the disease advances, individuals experience severe memory impairment, disorientation, mood changes, and loss of independence. The hippocampus, a region crucial for memory formation, is one of the first areas affected, followed by widespread brain atrophy.
