Parkinson’s disease (PD) is a neurodegenerative disorder featured by the loss of dopaminergic neurons of the substantia nigra.
The primary motor symptoms of patients with PD are muscular rigidity, akinesia-bradykinesia and resting tremor.
Catalepsy is a well-known symptom of Parkinson's disease. It is characterized by muscle rigidity and fixity of posture for a prolonged period of time (akinesia).
Neuroleptic drugs such as haloperidol induces catalepsy and are thus used as a model for screening of new compounds that could reverse catalepsy and by the way improve the symptom of Parkinson’s disease.
Anti-parkinsonian drugs are usually tested in this model but other treatments could also be considered. Please feel free to contact us to discuss the feasibility of your study.
☐ Haloperidol-induced catalepsy
☐ Akinesic symptoms of PD
The degree of inhibition / reversion of haloperidol-induced catalepsy is used to measure the potential effect of new drugs on akinesic symptoms of PD.

Treatment with CSC markedly reduces haloperidol-induced catalepsy.
