The principle

A coil held against the scalp generates brief magnetic pulses. They pass through the skull and induce small electrical currents in a targeted region of the brain.

The target is a cortical area associated with mood regulation.

What a session involves

  • You sit in a treatment chair — awake, clothed, no anaesthesia
  • The coil is positioned and calibrated to your motor threshold
  • You hear clicking and feel a tapping sensation on the scalp
  • Ear protection is provided
  • Afterwards you resume normal activity

Why a course, not a single session

TMS is a planned series of sessions over consecutive weeks. Consistency is part of the treatment, not an administrative detail.

Your clinician reviews progress at defined intervals.

Safety and side effects

The most commonly reported effect is scalp discomfort or headache during or shortly after sessions, which usually reduces as treatment continues.

Tell your clinician about any implanted device, metal in the head or neck, seizure history or medication — these can affect suitability.
