Mental illness: A stigma or a real problem?


Each individual gets "sad" or "blue" at times in his life, and we sometimes make a joke about people being crazy, even though we know that we should not. We have all had some exposure to mental illness, but do we really understand it or know what it is? Many of our preconceptions are often incorrect. 

A mental illness can be defined as a health condition that changes a person's thinking, feelings, or behavior (or all three) and that causes the person distress and difficulty in functioning.

Similar to any other disease, it can be severe in some cases and mild in others.

Individuals who have a mental illness do not inevitably look like they are sick, particularly in cases of mild illness. Some individuals may show more symptoms such as confusion, agitation, or withdrawal. 

There are several different mental illnesses, such as depression, schizophrenia, attention deficit hyperactivity disorder (ADHD), autism, and obsessive-compulsive disorder.

Some other brain disorders include Parkinson's disease, and multiple sclerosis, however, they are considered neurological diseases instead of mental illnesses. 

It has been shown that difference between mental illnesses and other brain or neurological disorders is blurred.

Moreover, growing evidences suggest that mental illness is associated with changes in the brain's structure, chemistry, and function and these disease does exhibit a biological basis.

Few people feel that mental illness is rare, it only happens to people with different and difficult life situations, and that it will never affect them.

However, surveys of mental illness showed that this belief is far from accurate, as one of every four people is affected by mental illness either directly or indirectly.
