Psychiatric disorders (PDs) are very frequent in neurological illnesses. Depression, anxiety and cognitive impairment are frequently seen in many neurological disorders such as stroke, Parkinson disease (PD), epilepsy and multiple sclerosis (MS). In addition, hallucinations, delusions, obsessive-compulsive disorder, sleep disorders, Impulse control disorders (ICDs), somatization, bipolar disorder, behavior problems and psychological problem are also seen. Depression in stroke and epilepsy has bidirectional relationship. Lesion location affects both frequency and severity of depression in stroke patients. Hallucinations and delusions are frequent in patients with Parkinson disease and epilepsy. In Parkinson’s, these are associated with disease itself and are also secondary to treatment while in epilepsy, psychosis can be peri-ictal and interictal or post-ictal. Suicidal ideation are prominent in MS and epilepsy patients. Suicide is considered to be an important contributor to the increased mortality of persons with epilepsy. Features of depression and dementia may overlap with symptoms of neurological illnesses especially in multiple sclerosis, parkinsonism and stroke thus confounding the identification of these disorders. The presence of co morbid psychiatric illnesses in neurological patients should be of particular concern to physicians as they increase severity of neurological problem, lead to more functional impairment and increase mortality. Clinicians must aim to identify those patients with co morbid illness most likely to benefit from interventions and psychiatric or psychotherapeutic treatment should be provided to them.Psychiatric disorders (PDs) are very frequent in neurological illnesses.
