Psychiatric disorders like bipolar disorder or schizophrenia do not appear all of a sudden. There are small changes that happen to an individual over a long period of time until the disease fully develops. These signs and symptoms might be too subtle in the early stage for other people to notice until they become obvious. But an early detection of any irregularity proves to be more beneficial for the patient in the long run.
It is important to know the telltale symptoms of mental disorder to distinguish between what is regular and what is not.
Everyone needs some quiet time to cool off and relax but if a person continuously withdraws him/herself from social occasions and avoids meeting or speaking to friends, it could be a sign that something is wrong. Losing interest in life, work and people are symptoms of depression and psychotic disorder.
Having trouble concentrating, remembering, understanding and explaining oneself in a coherent manner are some common signs of mental disorder.
