The damage caused by epilepsy is very great, and mental disorder is also one of the aspects of epilepsy, so what are the clinical characteristics of epilepsy mental disorder? I. Pre-epileptic mental disorder: typically manifested as a poor state of mind or depression. Second, psychiatric disorders during seizures: including psychomotor seizures, seizure affective disorder and transient schizophrenia-like seizures. The typical presentation is often a non-convulsive persistent status epilepticus. The key to diagnosis is the impairment of consciousness with typical abnormalities of EEG. Third, interictal psychotic disorder: there are often the following types: 1. Schizophrenia-like psychosis: often after the seizures are controlled, psychotic symptoms such as hallucinations and delusions appear. The difference with schizophrenia is that the content of its hallucinations and delusions is more realistic and lacks absurdity, often without negative symptoms, and does not lead to decline. 2. Intellectual impairment: It is generally believed that the younger the age of onset and the more frequent the episodes, the more likely it is that intellectual impairment will occur. Firstly, the near memory decreases, and then affects the distant memory, comprehension, calculation, analysis and judgment ability. In severe cases, progressive decline can develop into dementia. This is accompanied by changes in thinking, emotion and behavior, and a viscous, violent personality change. 3, epileptic personality changes: personality changes to the most obvious emotional response, with “bipolar” characteristics, performance on the one hand, irritable, brutal, hostile, hatred, impulsive, sensitive, suspicious; on the other hand, the performance of excessive polite, meek, affectionate, praise. The thinking is slow, sticky, pathologically redundant and content-poor. 4, neurosis: epilepsy patients can be accompanied by anxiety disorder performance anxiety, nervousness, fear and anxiety physical symptoms, such as palpitations, nausea, abdominal discomfort, shortness of breath, tremor, etc. Obsessive-compulsive disorder is a common symptom, highlighted by compulsive behavior, often with repeated cleaning, repeated checking, non-stop counting, etc., accompanied by anxiety. 5, other: mood disorders can have depressive or light manic episodes, sexual dysfunction, etc. Fourth, post-ictal psychiatric disorder: refers to the psychiatric symptoms that appear within 7 days after the seizure. The duration of the disease is relatively short, usually not more than 5 days. Affective symptoms are predominant, manifesting as delusional or affective psychotic disorder; the duration of epilepsy is often more than 10 years; small doses of antipsychotics, which can rapidly relieve symptoms. Experts remind the majority of epilepsy patients that although epilepsy is a neurological disorder, it is not a mental illness, so please do not confuse patients and their families. Although the danger of epilepsy is very serious, epilepsy can be cured.
