Abstract

Spirulina platensis (blue-green algae) is a nutritional supplement. It constitutes of high content of protein, antioxidants, various phytopigments and possesses neuroprotective activities. Schizophrenia (SZ) is recognized as a neuropsychiatric disorder in humans with a reduced lifespan followed with impairments in social as well as vocational functioning. Major psychotic symptoms of SZ cluster into three categories: positive, negative and cognitive dysfunctions. Dizocilpine recognized as one of the best drugs to mimic full spectrum of SZ can develop an animal model of the disorder. Various antipsychotics are considered as approved treatment therapy for the psychotic symptoms of SZ but they also exert adverse effects. Thus, there is an excessive need for novel treatment(s) with negligible adverse effects. Present study was designed to evaluate the neuroprotective effects of spirulina in ameliorating the psychosis- like symptoms in dizocilpine-induced rat model of SZ. Spirulina was tested at the dose of 180 mg/kg. Results showed that administration of spirulina improved behavioral deficits and combated the oxidative damage evident by a significant reduction in lipid peroxidation and increase in antioxidant level. Thus, from present findings it may be suggested that spirulina can be used as a therapy for preventive or therapeutic measures.
