When the neurons get damaged and no longer function efficiently the resulting limitations differ, depending on which side of the brain is damaged. The right side of the brain will cause problems understanding things, and recognizing people and things. Damage in the left side of the brain has been seen to cause by depression, and problems with speech. 1.4 How other factors can cause changes in an individual’s condition that may not be attributable to dementia A variety of
The neurotransmitter I believe would have abnormal function after a stroke is Acetylcholine. Acetylcholine is a common neurotransmitter used in the spinal cord and motor neurons to stimulate muscle contractions. It’s also used in the brain to regulate memory, sleeping, and dreaming. Acetylcholine is the primary chemical carrier of thinking and memory. Since a stroke can affect your memory and walking ability I believe acetylcholine would be abnormal.
People with Alzheimer’s disease lose nerve cells which use this chemical. The other types of medication are generally used in line with anti dementia drugs due to side affects. Commonly used medications can affect people with dementia in positive and negative ways. Positive ways in which it can affect someone are, a brighter mood, it may give them the ability to perform activities such as going shopping or to social functions. It may offer reduced memory loss and a reduction in hallucinations.
. Disruption of this blood supply usually leads to a wide range of deficits, knocking out neighbouring regions that often have different functions16. On the other hand, owing to the redundancy of the human brain, small lesions that only partially damage a module might not lead to any obvious behavioural
CU4365 UNDERSTAND THE FACTORS AFFECTING OLDER PEOPLE 1.1 DESCRIBE CHANGES THAT MAY COME WITH AGEING. Some of the body changes are as listed below: What happens | Why | Mental function:Difficulty remembering or coming up with the right wordDifficulty concentratingDifficulty learning new material | The nerve cells in the brain release different amounts of some chemical messengers (which send impulses from cell to cell), and the number of receptors on nerve cells may decrease. Thus, the brain does not send or process impulse as well or as quickly. | Physical activity:Unsteadiness or loss of balance. | Structures in the inner ear that help with balance stiffen and deteriorate slightly.The part of the brain that controls balance (cerebellum)
The chemical and electrical signals are necessary in controlling bodily functions – for example language, decision-making, memory, personality, behaviour, sensing and interpreting our environment, and controlling muscle movements. If the neurons and synapsed of the brain become damaged by dementia they may have difficulty or be unable to carry the messages that tell the section of the brain what to do. Depending on the area of the brain affected, this can result in changes to the way the individual thinks, or may result in physical impairments, personally and behaviour changes or the inability to perform certain functions. Area of the brain | Key functions that could be affect by dementia | Frontal lobe | Movement, emotional behaviour, personality, interpretation and feeling. | Parietal lobe | Language, special awareness and recognition | Temporal lobe | Long – term memory, speech and hearing | Occipital lobe | Vision | Cerebellum | Balance, posture, muscle coordination (movement) | Hypothalamus | Regulates thirst, appetite, body temperature and also
Alzheimer’s disease- Alzheimer’s disease is caused by the build-up of proteins in the brain which form into “plagues and tangles”, these in turn will cause a loss of connection between nerve cells and cause cell death and loss of brain tissue. Early symptoms of Alzheimer’s can be lapses in memory, problems with language (forgetting words or their meanings) and poor visuospatial skill’s (gaging distance, ability to see in 3D). People can also suffer from depression or anxiety, they could become withdrawn and lose interest in daily activities or hobbies or have poor initiation. As the disease progresses sufferers can develop more pronounced memory problems and lose a sense of time and place, they may forget where they are or have difficulties recognising their own family. Vascular dementia- Vascular dementia is caused by the flow of blood and oxygen to the brain being interrupted causing the death of brains cells, this is called an infarct.
Explain how Alcohol affects a person’s nervous system and the effects it has on a person’s normal waking consciousness. The central nervous system is a complex system consisting of the brain and spinal cord. The brain is responsible for all our actions and the spinal cord transmits incoming information to the brain. The CNS takes in information through the senses, controlling motor function, as well as thinking, understanding, and reasoning. It also controls emotion; being intoxicated threatens the normal function of this.
The loss of cognitive function can also cause one to lose their ability to love an independent life. For the people that suffer from memory loss it can make everyday life very difficult for them. When you look at memory loss the onset can come very gradually or in some cases it can come on very suddenly. The loss of memory can also be referred to as amnesia. When you define memory loss it is defined as the inability to recall events from the past.
People with delirium suffer from hallucinations and delutions which means they hear see or think things that are not real, their thinking and reasoning are affected significantly and severe confusion is often present as in most cases of dementia. Age related memory impairment can cause forgetfulness again similar to dementia. The most common causes of different types of dementia are as follows. Alzheimer's disease: Alzheimer's disease is caused by parts of the brain wasting away, which damages the structure of the brain and how it works.It is not known exactly what causes this process to begin, but people with Alzheimer's disease have been found to have abnormal amounts of protein and fibres in the brain.These reduce the effectiveness of healthy neurons, gradually destroying them.Over time, this damage spreads to other areas of the brain such as the grey matter and the hippocampus.
