Psychology: What does it involve?

With lives getting stressful, the occurrence of psychological disorders is increasing by the day. Let us learn more about these disorders and their classification.

What is psychology?

Psychology involves an integrated study of the human mind and behaviour, and its response to circumstances. Psychology makes use of various branches of science, including medical science and social science. It combines psychological theory and clinical practice to relieve/prevent various mental health conditions.

Psychological treatment (also known as psychotherapy) is carried out by specialists who talk to a patient about their thought, emotional and mental concerns, and traumas. These specialists are called psychologists.

Various factors may influence a person’s mental health. These include:

  • Genetics
  • Relationship issues
  • Living conditions
  • Stress
  • Environment
  • Childhood / past traumas
  • Fears and phobias

Depending on a patient's requirement, psychology uses specialised techniques like psychotherapy, meditation, hypnotic therapy, relaxation techniques, and counselling.

Psychologists often work closely with psychiatrists, who prescribe the necessary medications that a patient may need along with psychotherapy.

What do psychologists do?

These professionals help diagnose and treat various psychological disorders and mental health diseases in patients. Clinical psychologists are often trained in various techniques like counselling, psychotherapy, hypnotherapy, group therapy.

Make an appointment at Gleneagles Hospitals

Psychological disorders have often been considered a taboo topic for discussion. Most patients (and even their loved ones) avoid disclosing these issues to a doctor, which causes the problem to develop into a chronic condition.

It is advisable to consult your psychologist when the symptoms are mild. Overall, there needs to be an acceptance that psychological issues are normal and treatable through the right approach.

Make an appointment with a psychologist at your nearest Gleneagles Hospital.
