Dementia vs. altzheimer’s. what’s the difference – democratic underground what is anoxic brain injury

… That paralyzed her and robbed her of speech. My mother experienced a drastic change after her heart bypass, and that was probably due to microthrombi — teensy clots that can be filtered out by your lungs, but not by the heart-lung machine they put you on for the surgery– it can affect the brain in some people.

As far as dementia goes, my MIL was often confused the past several years (she’s 95 now), and now we can’t tell if anyone’s home at all. My mother ended up with full-blown paranoia, and every negative aspect of her character was magnified. She passed away two years after her heart surgery, convinced her best friend was stalking her, hating me, dividing the family.

Alzheimer’s disease is characterized not by strokes but by what they call plaques and tangles in the brain.What is anoxic brain injury

Dementia can be caused by a lot of different things, including head injuries, tumors, and diseases such as parkinson’s or untreated syphilis. Some of these things can be treated and cured, and some can be managed and mitigated, which is why it’s important to differentiate them.

I’m really sorry about your mom. It’s very hard to lose a loved one while they are still alive and in front of you.

3. I am not sure, but I think alzheimer’s can only be definitively diagnosed with an autopsy.


Also called: senility

Dementia is a word for a group of symptoms caused by disorders that affect the brain.What is anoxic brain injury it is not a specific disease. People with dementia may not be able to think well enough to do normal activities, such as getting dressed or eating. They may lose their ability to solve problems or control their emotions. Their personalities may change. They may become agitated or see things that are not there.

Memory loss is a common symptom of dementia. However, memory loss by itself does not mean you have dementia. People with dementia have serious problems with two or more brain functions, such as memory and language.

Many different diseases can cause dementia, including alzheimer’s disease and stroke. Drugs are available to treat some of these diseases. While these drugs cannot cure dementia or repair brain damage, they may improve symptoms or slow down the disease.What is anoxic brain injury

25. ICD classification of dementia (there are many types!)

Http://www.Who.Int/classifications/apps/icd/icd10online /

Chapter V


Mental and behavioural disorders


Organic, including symptomatic, mental disorders


This block comprises a range of mental disorders grouped together on the basis of their having in common a demonstrable etiology in cerebral disease, brain injury, or other insult leading to cerebral dysfunction.What is anoxic brain injury the dysfunction may be primary, as in diseases, injuries, and insults that affect the brain directly and selectively; or secondary, as in systemic diseases and disorders that attack the brain only as one of the multiple organs or systems of the body that are involved.

Dementia (F00-F03) is a syndrome due to disease of the brain, usually of a chronic or progressive nature, in which there is disturbance of multiple higher cortical functions, including memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgement. Consciousness is not clouded. The impairments of cognitive function are commonly accompanied, and occasionally preceded, by deterioration in emotional control, social behaviour, or motivation.What is anoxic brain injury this syndrome occurs in alzheimer’s disease, in cerebrovascular disease, and in other conditions primarily or secondarily affecting the brain.

Use additional code, if desired, to identify the underlying disease.

F00* dementia in alzheimer’s disease ( G30.-+ )

Alzheimer’s disease is a primary degenerative cerebral disease of unknown etiology with characteristic neuropathological and neurochemical features. The disorder is usually insidious in onset and develops slowly but steadily over a period of several years.

F00.0* dementia in alzheimer’s disease with early onset ( G30.0+ )

Dementia in alzheimer’s disease with onset before the age of 65, with a relatively rapid deteriorating course and with marked multiple disorders of the higher cortical functions.What is anoxic brain injury

Alzheimer’s disease, type 2

Presenile dementia, alzheimer’s type

Primary degenerative dementia of the alzheimer’s type, presenile onset

F00.1* dementia in alzheimer’s disease with late onset ( G30.1+ )

Dementia in alzheimer’s disease with onset after the age of 65, usually in the late 70s or thereafter, with a slow progression, and with memory impairment as the principal feature.

Alzheimer’s disease, type 1

Primary degenerative dementia of the alzheimer’s type, senile onset

Senile dementia, alzheimer’s type

F00.2* dementia in alzheimer’s disease, atypical or mixed type ( G30.8+ )

Atypical dementia, alzheimer’s type

F00.9* dementia in alzheimer’s disease, unspecified ( G30.9+ )

F01 vascular dementia

Vascular dementia is the result of infarction of the brain due to vascular disease, including hypertensive cerebrovascular disease.What is anoxic brain injury the infarcts are usually small but cumulative in their effect. Onset is usually in later life.

Includes: arteriosclerotic dementia

F01.0 vascular dementia of acute onset

Usually develops rapidly after a succession of strokes from cerebrovascular thrombosis, embolism or haemorrhage. In rare cases, a single large infarction may be the cause.

F01.1 multi-infarct dementia

Gradual in onset, following a number of transient ischaemic episodes which produce an accumulation of infarcts in the cerebral parenchyma.

Predominantly cortical dementia

F01.2 subcortical vascular dementia

Includes cases with a history of hypertension and foci of ischaemic destruction in the deep white matter of the cerebral hemispheres.What is anoxic brain injury the cerebral cortex is usually preserved and this contrasts with the clinical picture which may closely resemble that of dementia in alzheimer’s disease.

F01.3 mixed cortical and subcortical vascular dementia

F01.8 other vascular dementia

F01.9 vascular dementia, unspecified

F02* dementia in other diseases classified elsewhere

Cases of dementia due, or presumed to be due, to causes other than alzheimer’s disease or cerebrovascular disease. Onset may be at any time in life, though rarely in old age.

F02.0* dementia in pick’s disease ( G31.0+ )

A progressive dementia, commencing in middle age, characterized by early, slowly progressing changes of character and social deterioration, followed by impairment of intellect, memory, and language functions, with apathy, euphoria and, occasionally, extrapyramidal phenomena.What is anoxic brain injury

F02.1* dementia in creutzfeldt-jakob disease ( A81.0+ )

A progressive dementia with extensive neurological signs, due to specific neuropathological changes that are presumed to be caused by a transmissible agent. Onset is usually in middle or later life, but may be at any adult age. The course is subacute, leading to death within one to two years.

F02.2* dementia in huntington’s disease ( G10+ )

A dementia occurring as part of a widespread degeneration of the brain. The disorder is transmitted by a single autosomal dominant gene. Symptoms typically emerge in the third and fourth decade. Progression is slow, leading to death usually within 10 to 15 years.

Dementia in huntington’s chorea

F02.3* dementia in parkinson’s disease ( G20+ )

what is anoxic brain injury
