Two cases of electroconvulsive therapy (ECT) in adolescence are presented and the literature on the use of ECT in childhood and adolescence is reviewed. ECT was effective in children and adolescents with bipolar disorder and depression. Inadequate information exists to make a judgment regarding schizophrenia, delirium, and anorexia nervosa. ECT is not effective in autism and chronic organic brain syndromes. Complications cited include organicity and seizures in the period immediately after ECT, anxiety reactions, and disinhibition. Long-term memory deficit or cognitive impairment has not been found, although further research to rule out residual impairment is needed.

We reported the case of a 13-year-old anorectic girl with epileptic seizures who showed marked favorable responses to sodium valproate and clonazepam. These two anticonvulsants were effective not only for controlling her epileptic seizures, but also against anorexia nervosa itself. The mechanism of their action to anorexia nervosa is unknown, but repeated EEGs and a trial of sodium valproate with or without clonazepam may be useful in evaluating the diverse pathologies of anorexia nervosa which seems to be a heterogeneous clinical entity.

The records of 100 patients with anorexia nervosa were reviewed. Neurologic complications were present in 47 patients. Neuromuscular abnormalities were most common and were present in 45% of patients. Generalized muscle weakness was detected in 43% of patients and peripheral neuropathies in 13%. Less common neurologic complications included headaches (6%), seizures (5%), syncope in the absence of orthostatic hypotension (4%), diplopia (4%), and movement disorders (2%). Neurologic problems due to chronic deficiency diseases were rare; only one patient had symptoms directly attributable to a vitamin B12 deficiency and none had evidence of Wernicke's encephalopathy. In most patients, the neurologic complications were reversed completely after correction of nutritional deficiencies and fluid and electrolyte imbalances.

The goal of this paper is to draw conclusions about the usefulness of the standard EEG in psychiatry. In general, two thirds of psychiatric referrals for an EEG are expected to provide useful information. The emphasis in schizophrenia is placed on left-sided abnormalities, especially on the left temporal area. In mood disorders the emphasis is on right-sided foci, in addition to the controversial 6/sec spike and wave complexes, small sharp spikes and positive spikes. In the acute stage of alcoholism, a relationship is seen between the degree of intoxication and the amount of slow activity, while in the chronic stage an increase in slow activity is seen, but another change is fast activity on the temporal areas. During withdrawal a low seizure threshold can be seen as irregular bilateral spike and wave complexes. During abstinence 2-4 yr may be required before slow wave sleep is normal in all regards. Among the organic mental syndromes, delirium shows slow activity, except in delirium tremens, which often is associated with a normal record with fast activity. In dementia the prevalence of EEG abnormalities is related to the degree of impairment. After five sessions of ECT diffuse slow waves are often seen. In other conditions, among developmental disorders about one half of autistic children show abnormalities and epileptiform activity is not uncommon. Mild nonspecific abnormalities are seen in about 40% of dyslexics and also in behavior disorders. Anxiety disorders include anorexia nervosa, showing abnormal background activity related to the effect of starvation on cerebral metabolism. In panic attacks paroxysmal activity can be seen. In borderline personality positive spikes have been (again) associated with impulsivity and 6/sec spike and wave complexes with interpersonal problems. Of the drugs of abuse psilocybin and phencyclidine are often associated with generalized epileptiform patterns and with marijuana the alpha shows a decreased frequency with increased amplitude. Typically, an increase in slow activity is seen with psychotropic drugs if there is a change in the level of awareness. Finally, distinctive personality traits are, at times, seen in temporal lobe epilepsy and the phenomenon of "forced normalization" may appear when seizures stop and psychotic symptoms appear.

MacLean's pioneering concept of "The Triune Brain" began to emerge in 1949 with his publication Psychosomatic disease and the "visceral brain", followed in 1952 by Some psychiatric implications of physiological studies on frontotemporal portion of limbic system (visceral brain). This shows that his seminal ideas grew out of his astute observation of psychiatric signs and symptoms. Later on, he observed the broad spectrum of human epileptic seizures and its cause in the limbic system. A large variety of uncontrolled feelings and emotions, together with bizarre motor behavior, is elicited by seizures in the hippocampus and other limbic structures.Meanwhile, based on the triune brain model, a new approach to psychopathology has taken shape. It is the evolutionary perspective of mental diseases such as the major psychoses, anorexia nervosa, anxiety disorders, and also brain diseases such as Parkinson's disease or Huntington's disease. Many mental illnesses are marked by severe deficits in social behavior and social communication. The social communication system disintegrates, especially in the major psychoses. The response choices to social or other external signals in a given situation become limited or even distorted, and reasoning is no longer part of decision making. The emphasis of this contribution is on the disintegration of social behavior in psychopathology, based on evolutionary psychiatry. MacLean's concept provides valuable insight for understanding the biological roots of human social behavior and communication. It is time to uncover the ties between the natural and the social sciences.

We report two patients whose eating disorder resolved after right temporal lobe lesions. The first case report involves a woman with a history of bulimia nervosa and partial seizures arising from the occipital and right temporal regions. The second case is a woman with a history of anorexia nervosa that resolved after a head injury that resulted in right-sided inferofrontal and temporal encephalomalacia. Not only did both patients' eating disorders resolve, but their moods and libidos improved.

Psychiatric disorders pose a significant burden to the quality of life of individuals with tuberous sclerosis complex and their caregivers. The relationship between the location and distribution of brain abnormalities in tuberous sclerosis complex and specific neuropsychiatric disorders is largely unknown. We present the first case in the literature of a child with tuberous sclerosis complex and anorexia nervosa and discuss the relevance of electroencephalography, magnetic resonance imaging, and neuropsychologic testing. To understand psychiatric disturbances in tuberous sclerosis complex, we must consider each of the following factors: cerebral pathology, seizure history, cognitive impairment, psychosocial stressors, and medications.

Alexander disease is a rare, sporadic leukoencephalopathy characterized by white-matter abnormalities with frontal predominance and, as a rule, clinically associated with megalencephaly, seizures, spasticity, and psychomotor deterioration. We describe a boy who was diagnosed as affected by anorexia nervosa because of his refusal to eat, progressive weight loss, and psychologic disturbances. The observation of a hyperintense lesion on T(2)-weighed magnetic resonance images (MRIs) was initially explained as a pontine and extrapontine myelinolysis related to malnutrition. Following MRI and DNA analysis, we diagnosed a juvenile type of Alexander disease. Therefore, we can affirm the importance of the history and clinical examination to look for brainstem dysfunction in patients presenting with atypical anorexia nervosa.

Young onset dementia raises concern about familial and non degenerative dementias. We describe a patient with early dementia. At the age of 26, a woman developed symptoms of anorexia nervosa, at 30 a memory and attention deficit, and at 34 abnormal behavior with impulsivity, aggression, and dysexecutive disorder. At 36 she showed aphasia, stereotyped behavior, hyperreflexia, grasping reflex, urinary incontinence, myoclonus, and seizures. Blood and cerebrospinal fluid were normal. Brain computed tomography and single photon emission computed tomography showed diffuse cortico-subcortical atrophy and frontotemporoparietal hypoperfusion. A Leu424Val mutation was present in PSEN1 gene. PSEN1 mutations can produce Alzheimer's disease, frontotemporal dementia, and dementia with Lewy bodies phenotypes, or a combination of them. It has been proposed that the mutation type and location may influence the molecular pathogenesis and thus PSEN1 would represent a molecular connexion between these entities. This case shows a novel PSEN1 mutation with outstanding amnesic and frontal symptoms.

Growing evidence suggests that antiepileptic drugs (AEDs) may be useful in managing some eating disorders. In the present paper, we provide a brief overview of eating disorders, the rationale for using AEDs in the treatment of these disorders and review the data supporting the effectiveness of specific AEDs in the treatment of patients with eating disorders. In addition, the potential mechanisms of action of AEDs in these conditions are discussed. Of the available AEDs, topiramate appears to have the broadest spectrum of action as an anti-binge eating, anti-purging and weight loss agent, as demonstrated in two placebo-controlled studies in bulimia nervosa and three placebo-controlled studies in binge-eating disorder (BED) with obesity. Topiramate may also have beneficial effects in night-eating syndrome and sleep-related eating disorder, but controlled trials in these conditions are needed. The results of one small controlled study suggest that zonisamide may have efficacy in BED with obesity. However, both topiramate and zonisamide are associated with adverse effect profiles that may limit their use in patients with eating disorders. Phenytoin may be effective in some patients with compulsive binge eating, particularly if co-morbid EEG abnormalities are present, but available data are too varied to allow definitive conclusions to be made. Carbamazepine and valproate may be effective in treating patients with bulimia nervosa or anorexia nervosa when they are used to treat an associated psychiatric (e.g. mood) or neurological (e.g. seizure) disorder; otherwise, both agents, particularly valproate, are associated with weight gain. In conclusion, AEDs have an emerging role in the management of some eating disorders.
