Alzheimer’s disease is a progressive brain disorder that is the source of a continuing and unalterable decline in memory, language skills, concept of time and space and naturally, the capability to take care of one’s self. It was first observed by Alois Alzheimer in 1906. At first, it was thought to be a disease disturbing only young people but these days, late-onset Alzheimer’s is acknowledged as the most widespread cause of the failure of mental function in those aged 65 and above.
The inception of this disease is very gradual. In its early phases, patients have relatively placid troubles learning the latest information and remembering where they left certain objects. In time, they start to have difficulty remembering current events and finding the accurate words to express themselves. AS it progresses, patients may now have the trouble identifying dates and months or finding their way around proverbial surroundings.
They will now have the inclination to stroll and unable to find their way back. They frequently become strange and unapproachable. Changes in behavior may become more prominent as they become paranoid and is incapable to engage in normal talks (Davis). In addition, Parkinson’s disease is a neurological illness. It is caused by the steady loss of cells in a minute part of the brain called substantia nigra. When the cells begin to die, it generates a decrease in a fundamental chemical called “dopamine”.
A patient with Parkinson’s disease usually manifests uncontrollable trembling of hands, slowing down of activities, stiffness and loss of sense of balance. Since it is a progressive disease, it may worsen in time (Liaison).
