Alzheimer's disease is a progressive condition that undermines memory and other crucial cognitive functions. The connections between brain cells and the cells themselves undergo degeneration and eventual demise, ultimately leading to the destruction of memory and other essential mental capacities. It stands as the most prevalent cause of dementia among elderly adults.
Dementia comprises a collection of cognitive and behavioral symptoms that impede daily functioning. This group of conditions is characterized by the decline of at least two brain functions, such as memory and judgment. Common manifestations include forgetfulness, impaired social skills, and diminished thinking abilities that significantly interfere with everyday activities.
Parkinson's disease is a progressive disorder that affects the nervous system and the bodily functions controlled by nerves. Symptoms typically emerge gradually, with an initial and often easily noticeable tremor in one hand. While tremors are a common manifestation, this condition can also lead to stiffness or a reduction in overall movement.
