basics of alzheimer’s disease What it is and what you can do Basics of Alzheimer’s disease Alzheimer’s (AHLZ-high-merz) is a disease of the brain that causes problems with memory, thinking and behavior. It is not a normal part of aging. Alzheimer’s gets worse over time. Although symptoms can vary widely, the first problem many people notice is forgetfulness severe enough to affect their ability to function at home or at work, or to enjoy lifelong hobbies. Other symptoms include confusion, getting lost in familiar places, misplacing things and trouble with language.
It occurs when the supply of blood carrying oxygen and nutrients to the brain is interrupted by a blocked, or diseased vascular system. Vascular dementia generally affects people between the ages of 60 and 75, and affects more men than women. The most common type of vascular dementia is multi-infarct dementia (MID), which is caused by a series of small strokes, or “mini-strokes,” that often goes unnoticed and cause damage to the cortex of the brain—the area associated with learning, memory, and language. These mini-strokes are sometimes referred to as transient ischemic attacks (TIAs), that temporarily block blood supply, and briefly impair consciousness or sight. Over time, however, the damage caused to brain tissue interferes with basic cognitive functions that disrupts everyday activities in their daily lives.
Nina 1 Dementia describes a group of symptoms that are caused by changes in brain function. Dementia symptoms may include asking the same questions repeatedly; becoming lost in familiar places; being unable to follow directions; getting disoriented about time, people, and places; and neglecting personal safety, hygiene, and nutrition. People with dementia lose their abilities at different rates. They are several neurologic disease for which dementia is the major symptom. They are called neurodegenerative disorder simply because they degenerate the nervous system .Alzheimer disease is by far the most common neurodegenerative disorder.The cause of AD are still very unclear.
This can be more common in people who have high blood pressure, type 1 diabetes and those who smoke. Also If someone has a stoke it can damage brain cells. However not everyone who has had a stroke will go on to develop vascular dementia. Other less common causes of dementia can be things such as head injuries that can cause memory loss, brain tumours and alcohol abuse which is the cause of korsikof dementia. 1.2 describe the types of memory impairement commonely experienced by individuals with dementia.
How fast dementia progresses will depend on the individual person and what type of dementia they have. Each person is unique and will experience dementia in their own way. 2) Describe the key functions of the brain that are affected by dementia: The key functions that are affected by dementia are: * Temporal Lobe – Responsible for vision, memory, language, hearing and learning. * Frontal Lobe – Responsible for decision making, problem solving, control behaviour and emotions. * Parietal Lobe – Responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness.
Early personality changes can help doctors tell Pick disease apart from Alzheimer disease. People with Pick disease tend to behave the wrong way in different social settings. The changes in behavior continue to get worse and are often one of the most disturbing symptoms of the
Unit 4222-365 Understand the process and experience of dementia. Outcome 1 1,,A range of causes of dementia syndrome can be death of nerve or loss of communication between nerve cells,, Multiple cognitive deflects including memory impairment,, problems wiyh speach, failure to recognise people and decline in overall mental function. 2,, The types of memory impairment commonly experienced by individuals with dementia can be a decline in memory function results in the loss of memories of recent events/ Mobility can be affected as a result of short-term memory deficit; individuals can feel lost and wander away from their known surroundings,, / Problem solving can become a major issue as individuals find it increasingly difficult to learn new skills/ Loss of memory means that the ability to communicate is reduced as individuals tend to ask the same question over and over again or lose the thread of the conversation. 3,, Individuals with dementia experience difficulties interpreting the world due to incorrect processing of information in the brain. This can result in significant problems with perception and communication, including the ability to articulate feelings, frustration, stress and fear.
There are different types of dementia. Dementing disorders can be classified in many different ways. These classification schemes attempt to group disorders that have particular features in common, such as whether they are progressive or what parts of the brain are affected. Dementia is diagnosed when two or more brain functions - such as memory, language skills, perception, or cognitive skills including reasoning and judgment - are significantly impaired without loss of consciousness. Dementia is a progressing disease that gets worst with time, for some patients it might take a while but
Patients with Dementia1 can have difficulties with cognitive functions such as memory, language, reasoning, planning, recognising, or identifying people or objects. This decline is beyond what might be expected from normal aging. Dementia can eventually impair the ability to carry out everyday activities such as driving, household chores, and even personal care such as bathing, dressing, and feeding. The probability of suffering from dementia increases with age. Dementia mostly occurs in the second half of life, often after the age of 65.
