The Different Types of Dementia


Well-known  Types of Dementia and Common Attributes

Different types of dementia usually are linked to unique symptom behaviours as well as differentiating minute mental irregularities.

Click on arrows for drop down box explaining each type of Dementia.

Alzheimer's Disease

Alzheimer’s Disorder is regarded as the most prevelant of the different types of dementia; Alzheimer’s makes up sixty to eighty percent of cases. Trouble recollecting a name as well as the latest situations is frequently an initial health-related indicator; shortly after signs and symptoms consist of reduced judgment, confusion, frustration, behavioral transformations and difficulty talking, ingesting and even taking walks. Trademark irregularities are usually build up of the protein fragment beta-amyloid and complex strands in the protein tau.

Vascular Dementia

Typically the 2nd most widespread variety of Dementia is without question Vascular Dementia. Incapacity can be brought on by reduced flow of blood to areas of the brain, frequently as a result of number of small-scale strokes that obstruct arteries. Signs and symptoms frequently overlap with that relating to Alzheimer’s, even though recollection most likely is not as severely impacted.

Dementia with Lewy Bodies

The Method of decline may perhaps be much like Alzheimer’s, as well as difficulty with memory, judgment as well as behavioral variations. Overall health and seriousness of cognitive indicators might go up and down day-to-day. Visual hallucinations, muscle tissue stiffness as well as tremors are typical. Hallmarks include Lewy bodies (irregular build up of the protein alphasynuclein) which appear within nerve cells within the brain.

Normal pressure hydrocephalus (NPH)

Common pressure hydrocephalus (NPH) can be brought on by the accumulation of liquid within the human brain. Warning signs consist of problems with walking, forgetfulness along with lack of ability to control urine. NPH can often be remedied using surgical installing of a shunt inside the brain to drain excessive fluid.

Mild cognitive impairment (MCI)

Mild cognitive impairment (MCI) is known as a symptom in which a man or women has difficulty with recollection, speech as well as other necessary mental capabilities which can be extreme enough to become obvious to others and even are displayed on assessments, however, not serious enough to be able to hinder everyday life. Many people with mild cognitive impairment carry on to advance to dementia. For some individuals, the actual the signs of mild cognitive impairment will not advance to dementia, and a few individuals who have mild cognitive impairment during some point over time afterwards go back to normal mental status.

Frontotemporal Dementia.

Frontotemporal dementia consists of harm to brain cells, particularly in forward and side areas of the brain. Common signs and symptoms consist of variations in temperament as well as conduct and problems with speech. Absolutely no differentiating minute abnormality is related to any or all circumstances. Pick’s disorder, known as “Pick’s bodies,” is but one form of frontotemporal dementia.

Mixed dementia

Another of the different types of dementia is Mixed Dementia can be described as the existence of the trademark irregularities associated with Alzheimer’s and another form of dementia, most often vascular dementia, but additionally other kinds, for example dementia with Lewy bodies, frontotemporal dementia as well as normal pressure hydrocephalus.

Parkinson’s disease

A number of people who may have Parkinson’s disease acquire dementia within the later phases within the disease. Typically the trademark abnormality is without question Lewy bodies (irregular build up of the protein alpha-synuclein) which appear within neurological tissue within the brain.

Variant Creutzfeldt-Jakob disease

An extremely fast deadly condition which affects recollection as well as coordination and results in behavioral changes. “Variant Creutzfeldt-Jakob disease” is considered to be brought on by usage of products coming from cattle suffering from “mad cow disease.” A result of the misfolding of prion protein through the entire human brain.


When it comes to medical science, sundowning, also referred to as sundown syndrome, is an affliction relating to the occurrence or perhaps increase of one or even more unusual behaviours within a circadian rhythm. Sundowning generally takes place during the later part of the afternoon, evening hours, and nighttime, hence the name. An individual who is sundowning might display swift changes in moods, grow to be unusually demanding, distrustful, annoyed or even confused, and see or perceive things which aren’t even there during the the later part of the daytime and evening hours.


Wandering, when it comes to individuals having dementia, is a type of behavior that may cause potential risk for that particular person, and it is usually the most significant concern for care providers. It is believed to be the most widespread type of disruption coming from those that have dementia in institutions. Even though it takes place in various types of dementia, wandering is particularly typical in individuals having Alzheimer’s. This could be resulting from lapse of memory, as well as a consistent dependence on stimulation.


Un monitored wandering which goes out of bounds, the behavior generally known as elopement, can be a unique problem for care providers and search and rescue responders. Wandering (particularly if coupled with sundowning) can lead to the individual’s becoming missing outside after dark, clothed inappropriately, and not able to take various normally routine actions to make sure of their own individual security and safety. This can be a scenario of tremendous urgency, and the demand for searching during the night imposes additional hazards for the searchers.
