Alzheimer’s disease is a progressive neurodegenerative disorder that primarily affects memory, thinking, and behavior. It is the most common cause of dementia, accounting for 60-80% of cases. Alzheimer’s typically begins with mild memory loss, such as forgetting recent conversations or names, but gradually worsens, leading to difficulties with daily tasks, confusion, disorientation, and changes in personality. As the disease advances, individuals may lose the ability to communicate, recognize loved ones, or perform basic activities. While the exact cause is unknown, Alzheimer’s is believed to result from a combination of genetic, environmental, and lifestyle factors. Though there is currently no cure, early diagnosis and treatment can help manage symptoms and improve quality of life. Ongoing research continues to explore new treatments to slow the progression and potentially find a cure for this debilitating condition.
