Types of Dementia

There are many different forms of dementia and each has its own causes. Alzheimer’s Disease is the most common form of dementia, accounting for between 50% and 70% of all dementias.

The effects of the different types of dementia are similar, but not identical, as each one tends to affect different parts of the brain.

Here are the most common forms of dementia :

AIDS related dementia
Alcohol related dementia

Alzheimer’s disease, has two forms :

Familial Alzheimer’s Disease (FAD), also known as Early Onset Alzheimer’s or Younger Onset Alzheimer’s.
Sporadic Alzheimer’s Disease, also known as Late Onset Alzheimer’s. See section below.

Dementia with Lewy bodies: Another common form of dementia, sharing many similarities with Alzheimer’s disease.

Down syndrome: Research has established a link between Down syndrome and Alzheimer’s disease.

Frontal lobe dementia, including Pick’s disease.

Vascular Dementia: The second most common cause of dementia, after Alzheimer’s disease.

What is Alzheimer’s Disease

Alzheimer’s Disease is the most common form of dementia, a group of brain disorders that impair a person’s mental functioning, especially memory, thinking, and behavior.

The term dementia literally means loss of mentation or thinking. Dementia is a broad term which describes the loss of memory, intellect, rationality, social skills and normal emotional reactions.

Most people with dementia are older, but it is important to remember that most older people do not get dementia. It is not a normal part of the ageing process. Dementia can happen to anybody, but it is more common in people over 65 years of age. People in their 40s and 50s can also develop dementia.

Asthma Triggers

Asthma is a chronic lung condition that is characterized by difficulty in breathing. People with asthma have extra sensitive or hyper-responsive airways. During an asthma attack, the airways become irritated and react by narrowing and constructing, causing increased resistance to airflow, and obstructing the flow of the air passages to and from the lungs.

What triggers an asthma attack ?

The words “trigger factors”, or “triggers” of asthma are used for the things which can cause an attack in someone who already has asthma.

Many things seem to be able to bring on, or trigger, an asthma attack, and the causes and triggers vary greatly from person to person. Dogs and cats cause asthma attacks in some people. While for others, tobacco smoke, cold air, exercise and even laughing can trigger attacks too. Some people with asthma report that the asthma attacks are worse when they are upset, anxious or under stress. Some people get asthma if they take aspirin or other painkillers, and some get asthma from dusts or fumes at work.

Really bad asthma attacks, which force people to go into hospital, often happen after a virus infection of your nose or chest.

Male & Female Intelligence Brain Areas Differ

Although there are virtually no disparities in general intelligence between the sexes, a UC Irvine study has found significant differences in brain areas where males and females manifest their intelligence. […]
