Introduction. Brain tumors are clinically characterized by cerebral organic, focal symptoms, which are manifestations of local pathology. There is a definite connection between the psychotic state and the localization of tumors. Mental disorders can occur in the postoperative period. The prognosis of mental disorders in tumors depends on the tumor histology, localization, stage of the disease, the correctness of the topical diagnosis, operability, age and somatic state of the patient. Aim of the study. The aim of this work is to study the classification of brain tumors, as well as mental problems (symptoms, syndrome and clinical picture), depending on the location and metastasis of the tumor. Materials and methods. a literature review was studied (20 sources, published mainly over the past 2 years), devoted to the symptoms and syndromes of mental problems associated with brain tumors, as well as the classification of brain tumors. Results. as a result of the study, the classification of brain tumors, the prognosis depending on their location and metastasis, as well as the clinical picture, symptoms and syndromes that can be found in patients with mental problems with brain tumors were studied. In addition to cerebral symptoms (increased intracranial pressure, head pain, nausea, vomiting, displacement of brain tissue) and focal neurological symptoms in brain tumors and specific symptoms are observed, depending on the location and structure. We studied transient, persistent mental disorders, as well as acute postoperative psychoses. Among transient mental disorders, there were: convulsive seizures, hallucinations, insane violations, syndrome of depersonalization and derealisation, metamorphopsia, disruption of speech, thought, memory and consciousness. Persistent mental disorders (sleep and memory disturbances, Korsakoff syndrome, retrograde amnesia), affective disorders (dreary and anxious depression, euphoria, moria), long-term disturbances of consciousness, productive and negative symptomatology, anorexia nervosa were also studied. The clinic of postoperative psychoses with and without impaired consciousness (hallucinatory-delusional, oneiric states, Korsakoff syndrome with euphoria, akinetic mutism with stupor was studied. Conclusions. The result of the study is the allocation of specific mental symptoms and syndromes in various brain tumors (depending on the name of the tumor, localization, metastasis). The specific symptoms are systematized depending on the location of the tumor in the brain and the histological structure.
