Effectiveness

How Pimozide Affects PatientsPimozide is an oral medication used to treat mental illnesses. It blocks the dopamine receptors in the brain and causes changes to dopamine metabolism and function, which can provide therapeutic benefits as well as unwanted side effects. Unlike other antipsychotics, it does not cause as much sedation or low blood pressure, so it is a good alternative to haloperidol.
How Pimozide works in the bodyPimozide works to reduce tics in Tourette's Syndrome by blocking dopamine receptors in the brain.

Pimozide for Mental Disorder with Loss of Normal Personality & Reality
The generic brands for this drug aren't working, and it's Not available in India.

Pimozide for Tourette's
This drug was effective at decreasing tics, but after having my son's hormones checked, we found that they were all messed up. I'm highly suspicious that this drug is the reason, and so we're going to try to come off of it and see if his hormones go back to normal.

Pimozide for Tourette's
This medication made me tired and apathetic. It would work sometimes, but I always felt worse when I was on it, so I stopped taking it. Definitely not worth it for tourettes.

Answered by AI

Cognitive Psychophysiological Therapy + Biofeedback for Tourette Syndrome

14 - 21
All Sexes
Montreal, Canada
The goal of this clinical trial is to compare the effectiveness of CoPs therapy with or without the therapeutic component of biofeedback in treating tics in Tourette Syndrome with emerging young adults. Hypotheses: 1. The CoPs+Biofeedback treatment will improve the severity of tics (YGTSS) and the Clinical Global Impression, surpassing the clinical significance threshold of CoPs treatment alone. 2. We expect that the identified variables (psychosocial, neurocognitive, biological) will predict the improvement of tics. Researchers will compare if the biofeedback treatment will improve the severity of tics. * In the pre-test, participants will undergo two interviews, each lasting 3 hours. These interviews will assess (through a battery of tests) the severity of tics as well as the psychosocial, biological, and neurocognitive aspects of functioning. A general assessment of intelligence and executive functions will also be conducted. * They will next attend 10 to 12 therapy sessions, with or without biofeedback. (The biofeedback component is explained in more detail in the ''Study Design'' section). * The post-test follow-ups consist of two evaluations: one 3 months after the end of the treatment and the other 6 months after. The evaluation will be done using the same battery of tests as during the pre-test interview.

CBIT + TMS for Tics

12 - 21
All Sexes
Minneapolis, MN
Chronic tics are a disabling neuropsychiatric symptom associated with multiple child-onset mental disorders. Chronic tics affect 1-3% of youth 1 and are associated with impaired functioning, emotional and behavioral problems, physical pain, diminished quality of life, peer victimization, and a fourfold increased risk of suicide compared to the general population. Large randomized trials have demonstrated the superiority of CBIT over supportive therapy in child and adult patients. However, in these trials, only 52% of children and 38% of adults showed clinically meaningful tic improvement, meaning that 50-60% of patients do not benefit from CBIT. CBIT success relies on an ability to suppress tics that many youth lack. The central aim of CBIT is to enhance voluntary tic suppression. Better tic suppression ability drives CBIT improvement 10 and predicts lower tic burden over the course of illness. During the core CBIT procedure, competing response training, patients learn to inhibit tics by engaging in a competing motor action. However, research shows that many youth lack this fundamental tic suppression ability that CBIT aspires to enhance. This study will examine the clinical and neural effects of a treatment combining Comprehensive Behavioral Intervention for Tics (CBIT) and transcranial magnetic stimulation (TMS) to the supplementary motor area (SMA) in young people with tic disorder.
