Alzheimer's disease is the disease of the brain. It is a neurological disorder. It is an incurable disease .The incidence of the disease is very high amongst elderly people. It tends to affect people over 65 years of age, though there may be a few cases wherein the age of the patient is less than 65.It may be noted that though the obvious signs of Alzheimer are visible after 65, it may have started much earlier. About 26.6 million people in the world are affected by Alzheimer's and it is predicted that this number may increase manifold in near future.
Though there a common symptoms of Alzheimers, each affected person may have something different about his or her behavior. One of the biggest symptoms is memory loss. Memory loss is often taken very lightly, since people tend to take memory loss naturally in the old age. The person is unable to remember recent incidences of day to day life. The confirmation of the disease is done with the behavioral pattern of the patient along with scanning of the brain.
As the patient makes progress in the disease , the patient feels lost, confused, gets irritated easily, suffers from mood swings, is often aggressive in his behavior, is unable to use language effectively that is the patient forgets using certain words of day to day life, there is also a permanent memory loss that is the patient forgets past incidences. The patient stops interaction with the outside world and remains in his own company. The patient also withdraws from his hobbies or activities.
Slowly, the sensory organs of the patient become weak, becomes like a vegetable and ultimately, the death follows. It is difficult to quantify the length of the disease or the individual behavioral pattern. The disease can remain in a nasal stage for a long time, before it is diagnosed. Its progression is gradual and may go unnoticed till the symptoms become loud and clear. The average life of the disease after being identified is about seven years.
The cause and advancement of the Alzheimer's disease is yet to be known. It is understood that the disease is related with plaques and tangles in the brain. The disease is incurable and any medicine given to the patient can provide little relief in the symptoms of the disease, but certainly, no relief is sought from the disease itself. There is nothing yet available to stop the disease or to prevent it or to prolong its advances.
Somebody has to be present with the patient 24*7. The patient cannot be left alone. Often the family members or the spouse take care of the patient. Alzheimer’s disease has proved to be a costly affair not just for the families of the patient, but also for the economies of the world.
What we can do today to prevent Alzheimer from occurring is at best lead a balanced lifestyle, eat balanced diet, exercise regularly and keep ourselves engaged in some activity. These are general steps to be followed in order to have a healthy life and nothing in particular to prevent from Alzheimer’s disease.
