Dementia of Alzheimer’s Type
Dementia of Alzheimer’s type is the most common form of dementia, accounting for roughly 60-70% of all cases worldwide. It develops when abnormal protein deposits accumulate in the brain, damaging nerve cells and gradually disrupting memory, reasoning, and behaviour. Onset is usually after age 65, though early-onset cases do occur.
Medicine used to treat Dementia of Alzheimer's Type
How the condition progresses
Early signs are often subtle: forgetting recent conversations, losing track of dates, or struggling with familiar tasks. Over months and years, difficulties deepen to include confusion about time and place, trouble recognising family members, and changes in mood or personality. In later stages, people may need help with basic daily activities.
Approaches to treatment
There is no cure, but medicines within neurology can slow cognitive decline and manage symptoms. Cholinesterase inhibitors such as rivastigmine work by reducing the breakdown of acetylcholine, a chemical messenger important for memory and learning. Non-drug support, including structured routines, cognitive activities, and carer involvement, remains an important part of overall management.
If someone shows a sudden and rapid change in mental function, seek medical attention promptly, as this can signal a different or additional cause that needs assessment.
