All You Need To Know About Mental Illness Definition And its Various Aspects

A lot of people believe that mental illnesses are made up, but they’re not. Mental illnesses are just different types of diseases and disorders in the brain that can cause lots of problems. The only difference is that most physical diseases have cures while there currently aren’t any cures for mental illness (although some treatments have been found). That means it’s important to learn all you can about them so you know how to protect yourself and others from them.

• Anxiety: Constant worry or fearfulness, feeling restless or on edge, difficulty falling or staying asleep, muscle tension, dry mouth, and dizziness.

• Bipolar disorder: Extreme mood swings between periods of mania (euphoria, high energy, irritability) and depression.

• Schizophrenia: A mental illness that causes distorted thinking, hallucinations, delusions, and disorganized speech and behavior.

• Obsessive-compulsive disorder (OCD): intrusive thoughts or images that cause anxiety or distress, compulsive behaviors that are performed in an attempt to relieve the anxiety, and extreme perfectionism.
