Interictal psychiatric disorders in epilepsy [Epİlepsİde İnterİktal psİkİyatrİk bozukluklar]
Epilepsy can cause many different problems such as psychosocial problems except seizures. According to the temporal distribution, the psychiatric disorders which epilepsy caused can be addressed into the two main groups such as peri-ictal (preictal, ictal, postictal) and interictal. The interictal findings tend to be permanent. This study aimed to reveal interictal psychiatric disorders in detail. Totally 180 patients who are followed by our clinic for at least two years were evaluated retrospectively. Epileptic seizures are classified according to criterias of International League Against Epilepsy 1981 and Semiological Classification-1998 (Hans Lüders-Soheyl Noachtar), psychiatric disorders are classified according to criterias of DSM-IV. The cases were divided into two groups according to the presence of psychiatric disorders. The mean age was 35 ± 19 (9-87) years, female / male ratio was105/75, mean age at onset of epilepsy was 25 ± 20 years. Psychiatric disorder ratio was found 43.3% of cases. They are (in order of frequency); depression, generalized anxiety disorder, psychotic disorder, attention deficit, obsessive-compulsive disorder, panic disorder and affective disorder. Four percent of the patients had a history of attempting suicide. There was no statistical difference between the groups which psychiatric disorders detected and undetected about age, gender, seizure type, antiepileptic drugs and drugs number. Despite, there was no statistical reflection, the ratio of symptomatic epilepsy, frequent seizure and aura was relatively high in psychiatric disorder group. The most common psychiatric disorders are depression and anxiety disorders in the interictal period. This situations may even cause person commit suicide. It must be considered and measures should be taken that, psychiatric disorders can prepare a ground for several problems such as control of epileptic seizures and some psycho-socio-economic complexities.
