Dementia is the progressive decline in mental function –it reduces the ability to process thought or intelligence of a person. Such type of problem normally occurs due to some already met with diseases or sort of damages in brain cells. Damage could be due to a stroke, for an example, a disease might be Alzheimer’s.
Diseases that cause dementia
• Alzheimer’s disease – This is a most common cause of dementia. The chemistry and structure of the brain of a person with Alzheimer’s disease changes and the brain cells die prematurely.
• Stroke (Vascular problems)–Our brain needs a good supply of oxygen-rich blood but if strokes occur in blood vessels (veins and arteries) then this supply is damaged in any way and our brain cells could die.It causes the symptoms of Vascular Dementia.
• Dementia with Lowy bodies -Brain cells are also called nerve cells; they formpart of our nervous system.Spherical structures develop inside nerve cells, these spherical structures in the brain damage brain tissue. In resulting, the patient’s memory, concentration and ability to speak are affected. Dementia with Lewy bodies is sometimes mistaken for Parkinson’s disease because the symptoms are fairly similar.
• Fronto-temporal dementia–If the front part of the brain would damaged, the patient’s behavior and personality are affected first, later the memory changes.
• Other diseases – Progressive supranuclear palsy, Korsakoff’s syndrome, Binswanger’s disease, HIV\AIDS, and Creutzfeldt-Jakob disease (CJD). Dementia is also more common among patients who suffer from Parkinson’s disease, Huntington’s disease, Motor Neuron disease and Multiple Sclerosis. People who suffer from AIDS sometimes go on to develop cerebral impairment.
Symptoms of dementia:
• Memory loss – the patient sometimes starts forgetting their daily routines or short works for eg. Coming home from shop. As well as forgetting names and places. Some times for getting the things even after placing them on the right place.
• Moodiness –slowly the brain is loosing its power or damaging the cells which control the emotions and it results thatthe patient may become more moody. Tempers may also be affected by fear and nervousness – the patient would always remains in dilemma and freighting about the future.
• Conversational difficulties – the affected person finds it harder to talk read or write.
Later on the patient may not be able to look after himself as for daily routine needs.
Treatments of dementia
Cholinesteraseinhibitors (one stage of Dementia) are frequently managed during the early stages. Many psychological, cognitive and behavioral therapies may also be useful. Several studies clarifies that music therapy helps a lot to patients with dementia. It is important to remember that the patient’s helpers also need training for emotional support to moods problematic patients.
if a country find a lot of cultural differences or good education opportunities , plenty of employment with good atmosphere, no illogical gender differences and frequent immigration process is being adapt by the natives then, all these changes always occupies people, their working capabilities and thus causes less chances of dementia.
Prescribed drugs In USA are as follows:
Tacrine (Cognex), donepezil (Aricept), galantamine (Razadyne), and rivastigmine (Exelon) have been approved for the treatment of dementia caused by Alzheimer’s disease – some physicians prescribe these drugs for vascular dementia as well. Selegiline, which is used for treating Parkinson’s disease, has been found to slow down the progress of dementia.
