Treatment Optiions for Dementia

Tuesday, April 15th, 2008

Doctors have not found out any cure for the disease.They sometimes prescribe drugs to improve symptoms that often accompany Alzheimer’s disease.The treatment available can be classified as below:-
 
Cholinesterase inhibitors : This group of medications — which includes donepezil (Aricept), rivastigmine (Exelon) and galantamine (Reminyl) — works by improving the levels of neurotransmitters in the brain.Donepezil also appears to delay the onset of Alzheimer’s for about a year in people who have mild cognitive impairment (MCI). Cholinesterase inhibitors work out in some cases. As many as half the people who take these drugs show no improvement. Other people may choose to stop taking the drugs because of the side effects, which include diarrhea, nausea and vomiting.
 
Memantine (Namenda) : The first drug approved to treat moderate to severe stages of Alzheimer’s, memantine (Namenda), protects brain cells from damage caused by the chemical messenger glutamate. It sometimes is used in combination with a cholinesterase inhibitor. Memantine’s most common side effect is dizziness, although it also appears to increase agitation and delusional behavior in some people.

What are Symptoms of Dementia

The most commonly known symptom of Alzheimer’s disease is confusion. This behaviour in particular causes us to become ‘estranged’ from others and to be unpredictable in our interactions. Confusion can also occur ‘acutly’ i.e. suddenly and limited in time. The common symptoms that are seen in pateints are forgetfulness, misplacing things, difficulty in remembering names etc.People with Alzheimer suffer mainly from impaired memory and orientation, limitations of concentration, planning and judgement, personality changes and later also perceptual, speech and walking disorders; in the final stage, various other body functions such as swallowing and the excretion process are also affected. During the course of Alzheimer’s disease, patients lose their independence in managing everyday life. There are effects on perception and social relationships; people become more and more dependent on care.

Causes of Dementia

Causes The cause of Dementia is still unknown. There probably is not one single cause, but several factors that affect each person differently. The number of people with the disease doubles every 5 years beyond age 65.Family history is another risk factor. The more common form of Demantia is known as late-onset. It occurs later in life, and no obvious inheritance pattern is seen in most families. However, several risk factor genes may interact with each other and with non-genetic factors to cause the disease. The only risk factor gene identified so far for late-onset Alzheimer’s disease is a gene that makes one form of a protein called apolipoprotein E (ApoE). Everyone has ApoE, which helps carry cholesterol in the blood. Only about 15 percent of people have the form that increases the risk of AD. It is likely that other genes also may increase the risk of AD or protect against AD, but they remain to be discovered.

What is Dementia ?

Dementia is a neurological disorder in which the patient looses its ability to think, speak, reason, remember and move. It is a progressive brain dysfunction, leads to a gradually increasing restriction of daily activities. The most well-known type of dementia is Alzheimer’s disease. Dementia not only affects patients, but also those surrounding them, as most patients require care in the long-term.While Alzheimer’s disease is the most common cause of dementia, many other conditions also can cause similar symptoms.Dementia occurs in people with Alzheimer’s disease because healthy brain tissue degenerates, causing a steady decline in memory and mental abilities.Some of these disorders get worse with time and cannot be cured. Other types respond so well to treatment, their symptoms may even be reversed.After Alzheimer’s disease, the most common forms of dementia are vascular dementia and Lewy body dementia. Frontotemporal dementia is less common.
