A psychologist is a trained professional who studies the human mind and behavior. Psychologists use their knowledge and skills to solve mental illnesses and conduct reseach work to find newer techniques to address such problems.

Psychitarists are medically trained professionals and hence they can prescribe medications to treat mental illnesses. Psychologists engage in psychotherapy and other emotional therapies to alter emotional and behavioural states.

Psychologists help people by talking and screening patients for diagnosis and prevention of mental disorders. They perform several psychometric tests and diagnostic exams to identify disorders.

One should see a psychologist when they experience chronic anger, anxiety, sleeplessness, irrational fears, always feeling depressed or sad or have suffered a traumatic experience in the past.

Psychologists are not trained in medicine and hence they are not licensed to prescribe medications. Psychologists often work with psychiatrists in a team to offer psychotherapy.
