How this protocol works
In plain language
Tardive dyskinesia (TD) is a movement disorder characterized by involuntary, repetitive movements, often of the face, tongue, and jaw. It typically develops as a side effect of long-term use of certain psychiatric medications, particularly older antipsychotics.
COMMON MOVEMENTS:
- Repetitive chewing or lip smacking
- Tongue protrusion or twisting
- Grimacing
- Rapid eye blinking
- Finger movements
- Rocking or thrusting of trunk
RISK FACTORS:
- Duration of antipsychotic use (main risk factor)
- Older age
- Female sex
- Diabetes
- Mood disorders
- First-generation (typical) antipsychotics > second-generation
- Higher doses
CRITICAL: TD requires medical management. This protocol is SUPPORTIVE ONLY.
MEDICAL TREATMENT:
- FDA-approved treatments: Valbenazine (Ingrezza) and deutetrabenazine (Austedo) - VMAT2 inhibitors; effective for TD
- Medication adjustment: If possible, reduce or switch to lower-risk antipsychotic
- Clozapine: Lowest TD risk if antipsychotic needed
PREVENTION:
- Use lowest effective dose of antipsychotics
- Regularly assess for TD (AIMS exam)
- Consider second-generation antipsychotics
- Limit duration of treatment when possible
Vitamin E* may help prevent worsening (less effective for established TD).
Vitamin B6* has shown some benefit in small studies.
Antioxidants* may provide neuroprotective support.
Expected timeline: VMAT2 inhibitors show benefit within weeks. TD may be irreversible in some cases, especially if longstanding.
