Understand the process and experience of dementia. Unit 4222-365 Outcome 1- 1) A range of causes of dementia syndrome. Alzheimer's disease – This is the most common cause of dementia. Brain cells are surrounded by an abnormal protein and their internal structure is also damaged. In time, chemical connections between brain cells are lost and some cells die.
Alzheimers is the most common form of dementia, responsible for around two thirds of cases. This is a disease which causes the chemistry and structure of the brain to change, leading to the death of brain cells in certain parts of the brain. It is a progressive disease. One of our service
Alzheimer’s disease accounts for 60% to 80% of cases. Vascular dementia; this is the second most common form of dementia after Alzheimer’s. It is caused by problems in the supply of blood to the brain, which usually occurs after a stroke. Vascular dementia also occurs because of brain injury or a blood vessel blockage to the brain. Parkinson’s disease; the brain changes caused by Parkinson’s disease begin in a region that plays a key role in movement.
Although there a small amount of cases of Alzheimer’s and frontotemporal dementia can be inherited from a previous generation. Vascular dementia is where the blood supply to the brain is interrupted, if there is restricted or stopped blood supply to the brain that’s when the cells being to die which results in brain damage. * Alzheimer’s disease Alzheimer’s is the most common form of dementia, this form of the disease is the loss of cells in brain which causes the brain to shrink. The medical term for this is ‘Atrophy’. The most affected part of the brain is the Cerebral Cortex; this part
Each for of dementia will have certain symptoms that may be relevant to that disease but some symptoms may be present in more than one form of dementia. Alzheimer’s disease This is the most common cause of dementia around 60 to 80% of individuals affected have this type of dementia. This type of dementia can lead to an individual having difficulty remembering people’s names, places and recent events. They have difficulty learning new information this can lead to difficulty in communication as they may not recognize the person and not engage in conversation with them. Vascular dementia This is the second most common type of dementia and occurs after a significant vascular event for example a stroke.
Storage refers to the retention of this information. Finally, retrieval is the recovery of information stored in the brain. Memory is often split into sensory memory, short-term memory (STM) and long-term memory (LTM). Sensory memory refers to memory that is retained for a very short amount of time, normally less than 5 seconds. Iconic memory is visual memory, whereas echoic memory refers to sounds.
Alzheimer's disease accounts for 50 to 80 percent of dementia cases. Who? Alzheimer’s disease is an irreversible, progressive brain disease that slowly destroys memory and thinking skills, and eventually even the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear after age 60. When?
Amyotrophic Lateral Sclerosis: Lou Gehrig’s Disease Amyotrophic Lateral Sclerosis: Lou Gehrig’s disease Amyotrophic lateral sclerosis (ALS) – a devastating neuromuscular disease that strikes adults in the prime of life – has puzzled physicians since it was first described in medical literature more than 100 years ago. ALS was made famous by baseball legend Lou Gehrig – but anyone can get this disease. ALS is a fatal disorder that causes progressive muscle paralysis. ALS is a terminal neurological disorder that robs patients of their ability to dress themselves, eat, walk, and speak. Patients generally survive three to five years after being diagnosed, with death generally occurring due to respiratory failure.
Lesley Chubick PS124 Introduction to Psychology Alzheimer’s, Disorder of the Brain Unit 7 Assignment The mental disorder I chose for this assignment is on Alzheimers. Alzheimers is a form of dementia that is a disease that attacks the brain’s intellectual functions such as memory, orientation and calculation. This degenerative brain disease attacks one in ten men and women over 60. The question many of us have is what is Alzheimers, what is its effect on the brain and is there a cure? Being a degenerative disease Alzheimers attacks the brain through exponentially greater cell death and tissue loss which results in decreased brain size and brain activity.
In their test they examined a patients with late-onset OCD that lasted ten years and after the tests were done, the patient presented with clinical and neuroimaging features of Semantic Dementia. This clinical study was done due to the hypothesis of a linkage between Semantic Dementia and Obsessive Compulsive Disorder. This study however remained a hypothesis and a worry amongst the clinicians as in their study they mention only one patient. In testing this hypothesis they did not have a control
