Alzheimer's disease is a leading cause of severe cognitive decline in older adults.
It primarily impacts key brain functions, leading to significant difficulties with working memory, language skills, executive functions, attention, and long-term memory.
This disease is characterized by a gradual worsening of both cognitive and overall functional abilities.
In its early stages, individuals might struggle with complex tasks like driving, experience short-term memory loss, and occasionally exhibit behavioral changes such as anger or aggressiveness.
As the disease progresses, it often leads to dementia, a hallmark symptom of Alzheimer's and other chronic brain conditions.
Dementia involves a decline in memory, comprehension, rational thought, language, orientation, emotional control, and judgment.
Patients in advanced stages of dementia may lose the ability to perform basic daily functions, including talking, using the restroom, eating, and sleeping, and experience such severe memory impairment that they may not recognize their own name or identity.
With increasing life expectancy in Western countries, the prevalence of Alzheimer's disease is also rising.
