             Interventions for autism has progressed much since the disorder was stated by Kanner in the 1940s. Then Autism was believed to be intimately associated with schizophrenia and insufficient parenting was seen as the main factor responsible for the disorder. Psychoanalysis was frequently chosen as the treatment mode, however large-scale consumption of drugs were found and also electroconvulsive treatments were prescribed for application in schizophrenia cases. (Bovk; Goode, 2003) A lot of medications have been administered to alleviate autistic indications and activities having autism. However, presently no pharmacological treatments with proven suggestions are available for autism. Nevertheless, psychotropic drugs have been applied in autistic persons to cure main symptoms, behavioral dyscontrol, cure of simultaneous psychiatric ailments, and management of related clinical states like seizures. Drugs treating depression, especially serotonin -reuptake inhibitors - SRIs, and anticonvulsant drugs constitute the drugs generally applied for autism spectrum behaviors. (Hollander, 2003).

             The SRIs administered cover fluvoxamine, fluoxetine, paroxetine, venlafaxine, sertraine, and clomipramine. Several of these formulations have been researched in an open-label as also double-blind manner. The consequences of these researches on the whole point out that these drugs works while treating some of the indications of individuals having autism spectrum disorders. Anticonvulsants like valproic acid and carbamazepine are applied especially in people having comorbid seizure disorder, as also those suffering from impulsive violence and emotional imbalance. But, there has not been any placebo-controlled trials reported till today which assess the effectiveness of these drugs.
