Dementia is a progressive brain dysfunction which results in a restriction of daily activities and in most cases leads in the long term to the need for care. Many diseases can result in dementia, the most common one being Alzheimer's disease.
Alzheimer’s disease is a progressive neurodegenerative 
condition characterized clinically by a gradual decline in cognition, daily functioning and behaviour. Alzheimer's disease is the most common form of dementia: about 60% of all dementia patients suffer from Alzheimer's disease. In this case changes in the brain cells often occur, impairing them to 'function'. Those brain cells eventually die. This happens gradually to an increasing number of brain cells. Mainly cells in a certain part of the brain are affected, the cortex (the outside). That is the part we use to think with.
