Dementia is a decline in mental ability which affects memory, thinking, problem-solving, concentration and perception. Dementia occurs as a result of the death of brain cells or damage in parts of the brain that deal with our thought processes. Some forms of dementia, such as Alzheimer's disease, are degenerative. That is, they get worse over time. Other forms of dementia, such as vascular dementia, may be non-degenerative and may not get worse over time. People with dementia can become confused. Some people also become restless or display repetitive behaviour. They may also seem irritable, tearful or agitated. This can be very distressing for both the person with dementia and their family and friends.
