Tardive Dyskinesia Treatment in India, Causes, Symptoms and Top Hospital

Definition

Tardive dyskinesia (TD) is a neurologic syndrome. It results from using neuroleptic drugs—also called antipsychotic drugs. This class of drugs is used to treat psychiatric conditions, like schizophrenia. TD consists of a group of symptoms including:

• Abnormal twisting movements
• Abnormal postures due to sustained muscle contractions

Causes

It is unclear exactly why TD develops. Long-term use of neuroleptic drugs can cause changes in the chemistry in the brain that lead to the symptoms. Nerve cells may also become overly sensitive to certain substances, such as neurotransmitters in the brain. Not everyone who takes these drugs develops TD.

Risk Factors

Factors that may increase your risk of TD include:

• Use of neuroleptic drugs, especially if the drugs:
  • Are taken in high doses and longer than six months
  • Are first generation drugs
• Use of metoclopramide and prochlorperazine—These medicines are used to treat gastrointestinal problems, like nausea, vomiting, delayed bowel emptying, andgastroesophageal reflux disease (GERD), especially if taken more than three months.
• Age: 54 or older
• Sex: female
• Possible genetic factor
• Having a disease that may require using neuroleptic drugs, such as:
  • Mood disorders or other psychiatric disorders
  • Behavior problems that occur with psychiatric or neurologic disorders, such as agitation in Alzheimer’s disease
  • Digestive disorders such as:
    • Esophageal reflux
    • Nausea and vomiting
    • Diabetes —Diabetic gastroparesis may require the medicine metoclopramide.
  • Parkinsonism caused by neuroleptic drugs

Symptoms

TD causes repetitive movements. Movements usually occur in the face, mouth, limbs, or trunk. The movements are involuntary and serve no purpose. They may occur occasionally or all of the time. They may or may not be noticeable. Symptoms may begin while on the drug or within weeks of stopping it. They can worsen with:

• Stress
• Moving other parts of the body
• Taking certain drugs

Symptoms my decrease with:

• Relaxation
• Sleep
• Purposely moving the affected body part

Symptoms may include:

• Grimacing
• Sticking out the tongue
• Twisting the tongue
• Chewing
• Sucking
• Smacking lips
• Puckering lips
• Blinking eyes
• Facial tics
• Foot tapping
• Moving fingers as if playing the piano
• Rapidly moving arms, legs, or body
• Writhing movements
• Pelvic thrusts
• Grunting
• Sighing
• Noisy breathing

Diagnosis

The doctor will ask about your symptoms and medical history. A physical exam will be done. Other disorders can cause symptoms similar to those of TD. The doctor will rule out other disorders before making a diagnosis. There is no specific test for TD.

Tests may include:

• Your bodily fluids may be tested. This can be done with blood tests.
• Pictures may be taken of structures inside your head. This can be done with:
  • CT scan
  • MRI scan
