Anxiety is a mental health condition characterised by excessive, persistent worry or fear that interferes with daily life. It manifests in various forms, like generalised anxiety disorder, panic disorder, or specific phobias. While fear is a normal response, anxiety disorders involve intense, prolonged anxiety, often without a clear trigger.

Genetics can contribute to anxiety disorders, with studies suggesting a 30% likelihood of them running in families. Genetic variants in neurotransmitter-related genes like 5-HTT, 5-HT1A, and MAOA may increase susceptibility. However, a combination of genetic predisposition and environmental factors—traumatic experiences, stress, or other mental health conditions—also play a role in its development.

Symptoms range from physical manifestations like headaches, palpitations, and dizziness to psychological indicators such as constant worry, panic attacks, and avoidance behaviours.

Diagnosis involves a psychological evaluation comparing symptoms to diagnostic criteria, often found in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Treatment commonly involves cognitive behavioural therapy (CBT), medication like anti-anxiety drugs or antidepressants, or a combination of both. Early intervention and support groups are also beneficial.

Prevention strategies include seeking early help, staying active, and avoiding substances like alcohol and drugs that can exacerbate anxiety symptoms. Understanding the interplay between genetics, environment, and neurochemistry is crucial to managing and addressing anxiety disorders.
