The hypoglycemias caused by organic hyperinsulinism are predominantly manifested by means of neuropsychiatric disorders. They include losses of consciousness and seizures occurring in the period of hunger. The method of choice in the treatment of this disorder is surgical treatment of pancreatic neoplasms. This implies the need of early diagnostic procedure.

Ultimately traceable to neural glucose deprivation, symptoms of hypoglycemia include neurogenic (autonomic) and neuroglycopenic symptoms. Neurogenic symptoms (tremulousness, palpitations, anxiety, sweating, hunger, paresthesias) are the results of the perception of physiologic changes caused by the autonomic nervous system's response to hypoglycemia. Neuroglycopenic symptoms (confusion, sensation of warmth, weakness or fatigue, severe cognitive failure, seizure, coma) are the results of brain glucose deprivation itself. Glycemic thresholds for symptoms of hypoglycemia shift to lower plasma glucose concentrations following recent episodes of hypoglycemia, leading to the syndrome of hypoglycemia unawareness--loss of the warning symptoms of developing hypoglycemia. Thus, patients with recurrent hypoglycemia (e.g., those with tightly controlled diabetes or with an insulinoma) often tolerate abnormally low plasma glucose concentrations without symptoms.

Yawning is a normal reflex triggered by arousal, drowsiness, boredom, hunger and emotional conditions and it is associated to several neurological diseases and drug abuse. Its wide presence in the phylogenetic vertebrate scale and even in human fetuses as young as 12 weeks directed the search for the common anatomic and biochemical mechanisms involved. The demonstration that yawning is not connected with high CO2 or low O2 blood levels left aside a prevalent metabolic hypothesis. Its close relationship with the sleep-wake cycle, specially in moments previous to falling asleep and after awaking has been related to changes in personal situation and activity. A single component of this reflex which is to be found exclusively in humans, is the fact that yawning is contagious. Thus, it is considered a component of the adaptative mechanism that is part of the surveillance reflex, becoming a significant paralinguistic evolutive expression aimed at protection and social cohesion. The common anatomical structures and neurochemical systems taking part in yawning, the sleep-wake cycle and the temporal lobe epilepsy may imply that yawning results from a set of protective systems induced by endogenous opiods which intervene in the inhibition and prevention of the temporal lobe epileptic seizures.

The purpose of this study was to document seizure events associated with the use of a computer-based assessment and to describe the contextual factors surrounding these seizure episodes. Study participants were adults with epilepsy who were enrolled at research sites in Atlanta and Boston. Subjects were asked to complete a computer-based assessment at 3 time points. Fourteen seizure events were documented; they occurred during 1.6% of all completed assessments (896) and affected 4.4% of the participants (320). The mean age of participants who experienced seizure events was 41.4 years; about 70% were female, and 70% were white. A variety of possible precipitating factors for seizure events included hunger, fatigue, stress, and medication changes. Participants indicated computer use could have triggered their seizures in 2 instances. These findings suggest use of computer-based assessments may pose minimal risks for adults with epilepsy, particularly those without a history of photosensitivity epilepsy.

Insulinoma, usually benign (90%), is clinically characterized by symptoms as tremulousness, tachycardia, weakness, sweating, fatigue, hunger, headache, dizziness, disorientation and unconsciousness. However rarely it has an unusual presentation. We present a case of insulinoma misdiagnosed as neurologic disease. A 48-year-old man was admitted to our Emergency Division because of car accident caused by loss of consciousness. A diagnosis of complex partial seizure was made one year before. The patient appeared pale, tachycardic, BP 130/85 mmHg. Laboratory tests showed a severe hypoglycemia (30 mg/dl). He was treated with hypertonic glucose solution and the resolution of symptoms was obtained. Dosages of insulin and C-peptide, CT-scan and RMN confirmed a diagnosis of insulinoma. Seizure disappeared after surgical excision. The diagnosis of insulinoma is sometimes delayed up to more than 20 years. Neurologic or psychiatric presentation like disorientation, personality changes, amnesia, irritability, seizures, bizarre behavior, visual difficulties, neuropathy in patients affected by insulinoma could be cause of misdiagnosis. Diagnosis of insulinoma should always be considered whenever these symptoms occur, especially if unresponsive to specific therapy. Insulinoma is curable in most cases and an early diagnosis can avoid adverse consequences including neurologic damage.

In antiquity, fasting was a treatment for epilepsy and a rationale for the ketogenic diet (KD). Preclinical data indicate the KD and intermittent fasting do not share identical anticonvulsant mechanisms. We implemented an intermittent fasting regimen in six children with an incomplete response to a KD. Three patients adhered to the combined intermittent fasting/KD regimen for 2 months and four had transient improvement in seizure control, albeit with some hunger-related adverse reactions.

Insulinomas are benign insulin-secreting neuroendocrine tumors originating in the pancreatic beta cells. Symptoms are caused by hypoglycemia and clinical diagnosis is based on establishing their relationship to fasting, usually via a fasting test. The most conclusive imaging tests are endoscopic ultrasound (EUS) and CT. Surgery is the treatment of choice. A 33 year old male presented with a 2-year history of hunger which had intensified in the previous 6 months with added accompanying symptoms, culminating with an acute episode - loss of consciousness and seizures - which resolved after administering i.v. glucose. A fasting test was performed, with results suggestive for an insulinoma. Dual-phase CT showed a mass in the tail of the pancreas but no contrast enhancement. EUS was used for further assessment: B-mode showed a hypoechoic focal mass with a cystic component, on contrast enhancement the pattern was hypovascular, and elastography showed soft tissue. EUS fine needle aspiration (FNA) was performed and the immunohistochemistry (IHC) assay was conclusive for a neuroendocrine tumor of the pancreas. Treatment consisted of caudal pancreatectomy, with no recurrence after 1-year follow-up. Although this case started with a classic clinical presentation of an insulinoma, imaging studies related to tumor vascularization raised doubts about the actual diagnosis. Nevertheless, multimodal EUS assessment with FNA was considered to be the most appropriate diagnostic technique for detection, characterization and staging of the mass. EUS findings together with the IHC assay were able to offer the definite diagnosis of a benign neuroendocrine tumor and allowed us to refer the patient for appropriate treatment.

Insulinoma is an exceedingly uncommon pancreatic islet cell neuroendocrine tumor. The estimated incidence is approximately four cases per million individuals per year and accounts for 60% of islets cell tumors. It causes glycopenic symptoms which includes headache, feeling irritable, confused, seizure or coma and leads to catecholamine excess which includes rapid heartbeat, sweating, palpitations and feelings of hunger. Early detection of the tumor prevents recurrent episodes of lethal hypoglycemia.

Identifying the amount of prey available is an important part of an animal's foraging behaviour. The risk-sensitive foraging theory predicts that an organism's foraging decisions with regard to food rewards depending upon its satiation level. However, the precise interaction between optimal risk-tolerance and satiation level remains unclear. In this study, we examined, firstly, whether cuttlefish, with one of the most highly evolved nervous system among the invertebrates, have number sense, and secondly, whether their valuation of food reward is satiation state dependent. When food such as live shrimps is present, without training, cuttlefish turn toward the prey and initiate seizure behaviour. Using this visual attack behaviour as a measure, cuttlefish showed a preference for a larger quantity when faced with two-alternative forced choice tasks (1 versus 2, 2 versus 3, 3 versus 4 and 4 versus 5). However, cuttlefish preferred the small quantity when the choice was between one live and two dead shrimps. More importantly, when the choice was between one large live shrimp and two small live shrimps (a prey size and quantity trade-off), the cuttlefish chose the large single shrimp when they felt hunger, but chose the two smaller prey when they were satiated. These results demonstrate that cuttlefish are capable of number discrimination and that their choice of prey number depends on the quality of the prey and on their appetite state. The findings also suggest that cuttlefish integrate both internal and external information when making a foraging decision and that the cost of obtaining food is inversely correlated with their satiation level, a phenomenon similar to the observation that metabolic state alters economic decision making under risk among humans.
