Introduction

The synaptic transmission of the human brain is a fascinating process. Endogenous chemicals called neurotransmitters released from neurons carry an electrical response other neurons/muscles much like an electrical circuit. A precise balance of these neuro chemicals and a smooth interaction between them not only entail perception and cognitive functions, but also influence the way we act and feel.

The American Psychiatric Association defines mental disorders”a syndrome characterized by clinically significant disturbance in anindividual’s cognition, emotion regulation, or behavior that reflects adysfunction in the psychological, biological, or developmental processesunderlying mental functioning.”

The causes of most mental disorders are not entirely known and hence are mostly studied by incorporating findings from patient cases and experiments. Even differentiating between a personality trait and a mental illness is often very grueling since there aren’t any specific tests to identify these mental illnesses. A shift from someone’s usual personality due to some trigger event is generally the first warning sign. The trigger event can be a reaction to a personal tragedy or biochemical imbalances, genetic factors. This usually results in an inability to cope with regular routine.
