These two neuropsychiatric disorders represent disease end points of the dopaminergic spectrum where Parkinson¡¯s disease represents dopamine deficit and schizophrenia represents dopamine hyperactivity in the mid-brain. Therefore, current treatment strategies aim to restore normal dopamine levels. However, during treatment patients develop adverse effects due to overshooting of physiological levels of dopamine leading to psychosis in Parkinson¡¯s disease, and extrapyramidal symptoms in schizophrenia. Absence of any laboratory tests hampers modulation of pharmacotherapy. Apolipoprotein E and ¦Á-synuclein have an important role in the neuropathology of these two diseases. The objective of this study was to evaluate cerebrospinal fluid (CSF) concentrations of apolipoprotein E and ¦Á-synuclein in patients with these two diseases so that they may serve as biomarkers to monitor therapy in Parkinson¡¯s disease and schizophrenia %K cerebrospinal fluid %K Parkinson¡¯s disease %K schizophrenia %K dopamine %K apolipoprotein E %K ¦Á-synuclein %K biomarkers %K treatment monitoring %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6650621/
