skills. The disease comes on gradually‚ as two abnormal protein fragments called Plaques and Tangles accumulate in the brain and kill brain cells. All of this usually starts in the hippocampus‚ the part of the brain where memories are first formed. Over many years the Plaques and Tangles slowly destroy the hippocampus and it becomes harder and harder to form new memories. Simple recollections from a few hours or days ago that most people take for granted are just not there. After that‚ more plaques

UNDERSTANDING HOW KEY FUNCTIONS OF THE BRAIN ARE AFFECTED BY DEMENTIA You do not have to become an expert on the brain to be a good dementia health care worker. However‚ having a basic awareness of the brain’s functioning may help you to understand some of the difficulties a person with dementia is experiencing. It can also help to explain some of the behaviours you may find challenging and difficult to comprehend. The level of damage taking place in the brain (‘neurological impairment’)

memories after such an event. Lack of oxygen damages brain cells heavily‚ and due to an inability to regenerate‚ permanent memory loss may occur‚ depending on the severity of damage. Alcohol disrupts brain cells‚ specifically cells of the hippocampus. Because the hippocampus is responsible for long-term and short-term memory‚ extreme consumptions of alcohol over a long period can cause degradation. Parkinson’s disease is a known factor for causing memory loss because of its slow destruction of dopamine

Case Studies 1. A small family was traveling in its van and had a minor accident. The children in the back seats were wearing lap belts‚ but still sustained numerous bruises about the abdomen‚ and had some internal organ injuries. Why is this area more vulnerable to damage than others? Name specific organs that would be injured‚ as well as the abdominopelvic quadrant and region in which they are found. What injuries might you suspect in the damaged organs? The area is vulnerable because

time to take the exam. Declarative memories are the memories that we make an effort to remember. If you don’t study for the written exam you will not do well. The hippocampus is a horse-shoe shaped area of the brain that plays an important role in consolidating information from short-term memory into long-term memory. Damage to the hippocampus can cause anterograde amnesia. This is the loss of ability to create memories. B. Operant conditioning is a method of learning that occurs through rewards

Temporal lobe epilepsy is a syndrome that results from recurrent epileptic seizures that can be traced back to the temporal lobe. In general‚ epilepsy is a brain disorder in which clusters of nerve cells‚ or neurons‚ in the brain sometimes signal abnormally. Neurons normally generate electrochemical impulses that act on other neurons‚ glands‚ and muscles to produce human thoughts‚ feelings and actions (NINDS‚ 2006). In temporal lobe epilepsy the normal pattern of neuronal activity becomes disturbed
