Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. Dementia is a general category of medical conditions that affect normal brain functioning.\\ | Dementia is a general term for a decline in mental ability severe enough to interfere with daily life.

The World Health Organization (WHO) defines dementia as //[A] syndrome -- usually of a chronic or progressive nature -- in which there is deterioration in cognitive function (i.e., the ability to process thought) beyone what might be expected from normal aging. | The World Health Organization (WHO) defines dementia as //[A] syndrome -- usually of a chronic or progressive nature -- in which there is deterioration in cognitive function (i.e., the ability to process thought) beyone what might be expected from normal aging. | ||

+ | Alzheimer' | ||
+ | |||
+ | Anormal deposits of specific proteins in the brain disrupt normal brain function; as these deposits spread, brain tissue starts dying leading to further cognitive impairment. | ||
+ | |||
+ | ===What AD is not== | ||
+ | * Curable | ||
+ | * Contagious | ||
+ | * A natural part of the aging process | ||
+ | * Something you get from using deodorant or cooking in aluminum pans | ||
+ | * Inevitable if you live long enough | ||
+ | Less than 5% of all cases of AD run in families.\\ | ||
+ | A blood test can tell you whether you have a certain form of cholesterol-carrying protein associated with a higher incidence of AD but more than half with the risk factor never get AD. Because of the low correlation between the protein in the blood and getting AD, it's best not to take the blood test or have genetic testing to spare you from unnecessary worry. | ||
+ | |||
+ | ====Age and Dementia==== | ||
+ | A clear correlation between increasing age and chances of developing dementia. | ||
+ | ^Age^Number diagnosed dementia^ | ||
+ | |<65|1 in 1,500| | ||
+ | |65-70|1 in 100| | ||
+ | |71-79|1 in 20| | ||
+ | |80-89|1 in 4| | ||
+ | |90+|1 in 3| | ||
+ | |||
+ | ====Four types of dementia==== | ||
+ | ===[1] Alzheimer' | ||
+ | Most common form of dementia, in USA, 62-80% of cases.\\ | ||
+ | Is 5th leading cause of death in Americans >65 | ||
+ | |||
+ | ===[2] Vascular dementia=== | ||
+ | Second most common, in USA, 10% of cases.\\ | ||
+ | Previously known as // | ||
+ | Similar symptoms to AD but depend on parts of the brain affected by stroke. | ||
+ | |||
+ | ===[3] Lewy body disease=== | ||
+ | Rare, <4% of cases.\\ | ||
+ | Lewy bodies are protein deposits that damage brain cells, these also found in those with Parkinson' | ||
+ | Symptoms similar to AD, but sufferers also develop muscle stiffness, tremors, and shakiness in their limbs, and slower movement. | ||
+ | |||
+ | ===[4] Frontotemporal dementia=== | ||
+ | Least common of these, affects about 50,000 in US and is <2% of dementia cases. | ||
+ | Shares many features of AD but also has symptoms: strange or sexually disinhibited behavior, lack of empathy, poor personal hygiene, apathy and loss of motivation, increased appetite for sweet or fatty foods, and repetitive and compulsive speech and actions. | ||
+ | |||
+ | ====Mild cognitive impairment: Dementia lite?==== | ||
+ | Like dementia, mild cognitive impairment [MCI] can affect a variety of normal thought processes including memory, planning, and judgement, but it doesn' | ||
+ | |||
+ | ===The abnormally aging brain=== | ||
+ | In a person with MCI (Mild Cognitive Impairment), | ||
+ | * Forgetfulness | ||
+ | * Difficulty following conversations | ||
+ | * Declining ability to make sensibe decisions | ||
+ | * Getting lost easily | ||
+ | * Poor concentration and attention span | ||
+ | |||
+ | ===Global Deterioration Scale (GDS)=== | ||
+ | Developed by Dr. Barry Reisberg in 1982, shows generally follow this progression of those with MCI that progress to dementia. | ||
+ | |Stage 1|No problems identified| | ||
+ | |Stage 2|Patient recognizes that he/she has a problem, perhaps remembering names, but he/she scores normally on diagnostic tests| | ||
+ | |Stage 3|Subtle problems carrying out thought processes start to affect work and social activities. Tests may begin to pick up problems -- this is MCI (Mild Cognitive Impairment)| | ||
+ | |Stage 4|Clear-cut difficulties develop in terms of memory and carrying out tasks such as dealing with finances or traveling. | ||
+ | |Stage 5|The person needs some assistance but is capable o washing, dressing, eating, going to the bathroom, and choosing appropriate clothes. | ||
+ | |Stage 6|The person is largely unaware of anything that's happening to him/her in the recent past. He/she needs help with most of the basic activities of daily living and may need to be in a nursing home. Incontinence is common.| | ||
+ | |Stage 7|By this stage the person is experiencing severe dementia. | ||
+ | |||
+ | ===Taking steps to avoid MCI=== | ||
+ | No specific treatment exists.\\ | ||
+ | It might help to address risk factors for poor circulation by: control blood pressure, eat low-carb and high-fiber diet, quit smoking, limited alcohol, and getting regular exercise.\\ | ||
+ | Evidence suggests that keeping the brain mentally active can help: word and number puzzles, reading, maintaining stimulating hobbies, social activities.\\ | ||
+ | Consider reading //Staying Sharp for Dummies// which discusses this evidence in detail. | ||
+ | |||
+ | =====Identifying Early Warning Signs===== | ||
+ | Top ten most important early symptoms to look out for. It's more than just being forgetful; to be diagnosed, someone must show at least 2 if not more of these 10, which can be subtle to start with. | ||
+ | - Memory problems that affect daily life (important dates and events, route taken on well-traveled journeys, where you've left important paperwork, names and faces of friends, neighbors, and work colleagues) | ||
+ | - Difficulty with planning and problem solving (become confused using debit/ | ||
+ | - Problems finding the right word (finding right word becomes elusive, substituting something similar eg football becomes //kick ball//, wristwatch becomes //hand clock//; difficulty following thread of conversations) | ||
+ | - Confusion about time and place | ||
+ | - Poor judgement (spending money on things not needed, using inappropriate dress like wear coat to beach or shopping in rain wearing just t-shirt and sandals) | ||
+ | - Visuospatial difficulties (clumsiness, | ||
+ | - Misplacing things (losing ability to retrace steps to find things) | ||
+ | - Changes in mood (rapid switching between extremes of sadness, fear, anger) | ||
+ | - Loss of initiative | ||
+ | - Personality change (eg reserved person becomes flirty and uninhibited; | ||
