It is caused by nerve cells dying in certain areas of the brain and the connections between the affected nerve cells deteriorate. As the conditions affecting only or primarily the neurons of the brain, causes gradual but irreversible loss of functions of these cells, Memory loss is one of the earliest symptoms of this disease. Vascular dementia is caused by damage to the brain through deprivation of oxygenated blood causing part or all of the affected area to die. (Series of strokes) Conditions that can cause
It is important to encourage to maintain independence. Know the most common types of dementia and their causes. 3.1) The most common causes of dementia are neurodegenerative disease where the brain cells die more quickly than normal which leads to a decline in the persons mental and physical abilities. Dementia can be caused by strokes, brain damage, old age, or it can be hereditary. 3.2) Symptoms of Alzheimer’s; Becoming more confused and forgetful, Mood swings, Becoming withdrawn due to loss of confidence, Having difficulty completing every
Alzheimer's disease affects the brain through exponentially greater cell death and tissue loss, resulting in a decreased brain size. As a result, behavior, memory and thinking are affected. Vascular dementia is caused by blockages and breaches in the brain's blood supply that damage the brain and can be caused by any condition which results in an interruption to the blood flow to the brain, and as well as strokes, this could include diseased arteries, heart attacks, high blood pressure, raised cholesterol, diabetes, furred arteries and irregular heart rhythms. Any condition causing damage to the circulation of blood to the brain carries a risk to mental functioning. People experiencing vascular dementia will, like those with Alzheimer’s disease, have problems with learning, remembering, recognition, planning and problem solving.
In addition to this, the connections between affected nerve cells deteriorate. As the disease progresses, it spreads and affects cells in other parts of the brain. Day to day memory problems are first noticed but other symptoms include not knowing the right words anymore, problem solving, decision making or 3 dimensional perception. * Vascular dementia is caused when the brain is deprived of oxygen. This happens when the arteries which carry oxygenated blood to the brain can't get there and the brain, or part of it, dies.
INTRODUCTION Stroke or brain attack is the sudden loss of neurological function caused by an interruption of blood flow to the brain. Stroke is the third leading cause of death. There are two type of stroke commonly affected among people. A. Ischemic Stroke - Is the most common type affecting individuals - Lack of blood supply to the brain can be caused by thrombosis or embolism. It also may due to a hemorrhage.
Understand the process and experience of dementia Definition of dementia is a syndrome usually of a chronic or progressive nature in which there is deterioration in cognitive function, thinking, orientation, comprehension, and calculation, learning capacity, language and judgement. Dementia is caused by damage in brain. The most common cause of dementia is called neurodegenerative diseases that include Alzheimer’s disease, vascular dementia, Huntington disease, Front temporal dementia and dementia with lewy bodies. With this disease the brain cell degenerate and die more quickly than normal ageing process, these decline a persons mental and some times physical abilities. The gradual changes and damage to the brain cells are caused by a build up of abnormal proteins in the brain.
Stroke Awareness Health Assessment The self-risk assessment I chose to complete was about strokes. A stroke occurs when blood supply to the brain is temporarily interrupted or disturbed. Being that the brain requires a constant flow of oxygen any interruptions could prove to be fatal. The two types of strokes are Ischemic or hemorrhagic. An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically.
1.1 Explain what is meant by the term ‘dementia’. Dementia is a condition which is described by a number of symptoms and is a progressive decline of mental abilities and cognitive function as well as changes in personality, mood, communication and behaviour. Dementia is caused by chemical and structural changes within the brain as well as brain injury. 1.2 Describe the key functions of the brain that are affected by dementia. Dementia can affect the following key functions of the brain: - Temporal lobe - Parietal lobe - Frontal lobe - Occipital lobe - Hippocampus - Cerebrum lobe These all affect the function of: -Memory -Emotion -Cognitive skills -Perception -Behaviour -Communication -Senses and movement 1.3 Explain why depression, delirium and age related memory impairment may be mistaken for dementia.
Diseases Affecting the Immune System Amyotrophic lateral sclerosis, or ALS, is a disease of the nerve cells in the brain and spinal cord that control voluntary muscle movement. The cause of ALS is unknown and also referred to as Lou Gehrig’s disease. The progressive degeneration of the motor neurons in ALS eventually leading to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected.
Unit: Dementia Awareness This unit must be assessed in accordance with Skills for Care and Development’s Assessment Principles. Learning Outcome 1: Understand what dementia is Assessment Criteria 1.1. Explain what is meant by the term ‘dementia’ Dementia is a term used to describe a range of signs and symptoms that occur when the brain is affected. Chemical and structural changes in the brain damage and kill brain cells, dementia is a progressive disease and this simply means that the symptoms will gradually get worse. Neurons and synapses become damaged by dementia they may be unable to carry messages that tell a section of the brain what to do.
