Anxiety Disorders

The most common mental health condition — and one of the most treatable.

Anxiety disorders include generalised anxiety, panic disorder, social anxiety, and specific phobias. They differ in pattern but share underlying physiology and respond to similar therapies.

Causes & risk factors

  • Trauma or chronic stress
  • Temperament
  • Medical conditions (thyroid, cardiac)
  • Substance use and withdrawal

Symptoms

  • Panic attacks with palpitations, shortness of breath
  • Avoidance behaviours

Anxiety Disorders — FAQ

Do I need medication for anxiety?

Not necessarily — many improve with therapy alone. When medication helps, SSRIs are first-line, low-dose, and reviewed every few months.
