As people grow older, it is normal to experience a decline in cognitive mental ability as a part of the ageing process. However, dementia is not a normal part of ageing. It is a term that describes memory loss and other cognitive deficits. Symptoms of dementia can vary depending on the underlying cause, but memory lapses, repeating stories, disorganised speaking, sudden mood swings, putting things in inappropriate places and poor hygiene are all common.
Often, the terms Alzheimer’s disease and dementia are used interchangeably. Alzheimer’s disease, however, is the most common cause of progressive debenture. Progressive debenture means that it worsens with time and is irreversible. Vascular dementia, Louis body, Huntington’s disease, and Parkinson’s disease are all common progressive debentures. On the other hand, a range of reversible conditions can result in dementia-like symptoms such as medication effects, infections, immune disorders, dehydration, nutritional deficiencies, and heart and lung problems that restrict blood and oxygen flow to the brain. The therapeutic options and prognosis for virtually any dementia causing disease are best in the earliest stages. Even if the condition is irreversible, new medications and therapeutic approaches exist that could help ease and even delay symptoms, improving the quality of life for the affected person.
