Tardive Dyskinesia is a movement disorder that can occur after long-term use of certain medications, particularly antipsychotics. It is characterized by involuntary, repetitive movements, often affecting the face, tongue, and limbs. Symptoms may include grimacing, lip smacking, and rapid eye blinking, which can be distressing for those affected. The exact cause of Tardive Dyskinesia is not fully understood, but it is believed to be related to changes in the brain's dopamine pathways. While there is no definitive cure, some treatments may help manage symptoms, and early recognition of the condition is important for minimizing its impact.
