Correlation between telomere length and efficacy of oral and long-acting injectable antipsychotics on severity and cognitive impairment of schizophrenia.

LAI antipsychotics are similar to OAA in decreasing the disorder severity and improving the cognitive impairment in schizophrenia. Also, patients who have shorter TL show greater improvement in the negative PANSS score. Hence, TL holds the potential of predicting antipsychotic drug response in schizophrenia patients.KEY POINTSLong-acting injectable antipsychotic was comparable to oral atypical antipsychotics in bringing out improvement in disorder severity, cognitive functions over 12 weeks.Shorter telomere length has been found to be associated with a greater response in negative symptoms of schizophrenia.
