Dementia is a general term for loss of memory, language, problem-solving and other thinking abilities that are severe enough to interfere with daily life. Alzheimer’s is the most common cause of it.
Dementia is not a single illness; it’s a general term — like heart disease — that covers a wide scope of specific ailments, including Alzheimer’s disease. Problems assembled under the overall term “dementia” are brought about by strange brain changes.
These progressions trigger a decrease in reasoning abilities, otherwise called cognitive abilities, serious enough to debilitate everyday life and independent function. They likewise influence behaviours, emotions and relationships.
Alzheimer’s disease represents 60-80% of cases. Vascular dementia, which happens in view of tiny draining and vein blockage in the brain, is the second most basic reason for dementia. The people who experience the brain changes of different kinds of dementia simultaneously have mixed dementia.
There are numerous different conditions that can cause its symptoms, including some that are reversible, like thyroid issues and vitamin deficiencies.
Dementia is regularly mistakenly referred to as “senility” , which reflects the once broad yet common misconception that serious mental decline is an ordinary part of ageing.
SYMPTOMS OF DEMENTIA
Indications of dementia can shift incredibly. Some include:
- Problems with short-term memory.
- Keeping track of a purse or wallet.
- Paying bills.
- Planning and preparing meals.
- Remembering appointments.
- Traveling out of the neighbourhood.
Numerous conditions are progressive, which implies that the indications of dementia begin gradually and bit by bit deteriorate.

Medical assessment may recognize a treatable condition. Furthermore, regardless of whether indications propose dementia, early diagnosis permits an individual to get the best benefits by accessible medicines and gives a chance to volunteer for clinical trials or studies. It additionally gives time to plan what’s to come.

CAUSES OF DEMENTIA
It is brought about by harm to the brain cells. This harm meddles with the capacity of brain cells to communicate with one another. At the point when brain cell can’t impart normally, thinking, behaviour and emotions can be influenced.
The brain has numerous specific regions, every one of which is responsible for various things (for instance, memory, judgment and development). At the point when cells in a specific region are harmed, that area can’t do its capacities regularly.
Various kinds of dementia are related with specific sorts of brain cells that harm specifically areas of the brain. For instance, in Alzheimer’s disease, significant levels of specific proteins inside and outside brain cells make it hard for brain cells to remain solid and to speak with one another.
The brain region called the hippocampus is the focal point of learning and memory in the mind, and the cells in this area are regularly quick to be harmed. That is the reason cognitive decline is frequently perhaps the earliest symptom of Alzheimer’s.
While most changes in the mind that cause dementia are lasting and deteriorate over the long haul, thinking and memory issues brought about by the accompanying conditions may improve when the condition is dealt with or tended to:
- Depression.
- Medication side effects.
- Excess use of alcohol.
- Thyroid problems.
- Vitamin deficiencies.
DIAGNOSIS OF DEMENTIA
There is no single test to decide whether somebody has dementia. Specialists analyze Alzheimer’s and different sorts of dementia dependent on a cautious clinical history, an actual assessment, research centre tests, and the trademark changes in thinking, everyday capacity and conduct related with each kind.
Specialists can confirm that an individual has dementia with a significant degree of assurance. Be that as it may, it’s harder to decide the specific sort of dementia on the grounds that the symptoms and brain changes of various dementias can cover.
Now and again, a specialist may analyze “dementia” and not determine a sort. If this happens, it very well might be important to see an expert like a neurologist, psychiatrist, psychologist or geriatrician.
