Mild encephalopathy with reversible splenial lesion (MERS) is characterized with a reversible lesion in the splenium of the corpus callosum. It has been defined as a neuro-radiologic syndrome associated with viral infections. In addition, this lesion may related with epileptic seizures, antiepileptic drugs or metabolic disturbances. We presented a patient with MERS associated with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). Encephalopathy and psychiatric symptoms were the major initial clinical symptoms. Brain magnetic resonance imaging showed complete resolution of the corpus callosum lesion. The symptoms of patient recovered completely. Complete resolution of corpus callosum lesion and recovery of encephalopathy associated with SARS-COV-2 were similar to previous cases.

Reversible Splenial Lesion Syndrome

Background Reversible splenial lesion syndrome is a distinct entity radiologically characterized by a reversible lesion in the splenium of the corpus callosum. According to previous reports, this condition may be associated with antiepileptic drug use or withdrawal. We herein report a case of reversible splenial lesion syndrome associated with oxcarbazepine withdrawal. Case Report A 39-year-old man presented with an 8-year history of epileptic seizures. During the previous 3 years, he had taken oxcarbazepine irregularly. One week prior to admission, he withdrew the oxcarbazepine on his own, and the epilepsy became aggravated. Magnetic resonance imaging (MRI) revealed an isolated lesion in the splenium of the corpus callosum with slight hypointensity on T1-weighted imaging and slight hyperintensity on T2-weighted imaging. Regular oxcarbazepine was prescribed. Over a 5-month follow-up period, repeat MRI showed that the abnormal signals in the splenium of the corpus callosum had completely disappeared. Conclusion Reversible splenial lesion syndrome is a rare clinicoradiological disorder that can resolve spontaneously with a favorable outcome. Clinicians should be aware of this condition and that oxcarbazepine withdrawal is a possible etiological factor.

Reversible lesions involved in the splenium of corpus callosum (RESLES) are a rare clinic-radiological condition, whose pathogenesis could be related to infectious events (such as in mild encephalopathy with reversible splenial lesion—MERS), epilepsy or metabolic/electrolyte disorders. MERS is characterized by an acute mild encephalopathy associated with lesions in the splenium of corpus callosum on brain magnetic resonance imaging. Viral infections are commonly associated with this condition and type A influenza is the most common cause. The prognosis is generally favorable with spontaneous resolution of clinical and radiological abnormalities. We report a case report of type B influenza MERS in an 8-year-old unvaccinated girl with complete clinical and radiological recovery.

SUMMARYIntroduction.Corpus callosum (CC) is the largest forebrain commissure. Structural anomalies and accompanying clinical symptoms are not in the focus of neurologists, epileptologists or neurosurgeons.Aim and method.Anatomy, embryological development, normal functions, structural abnormalities, additional malformations, clinical symptoms and seizure disorders with CC anomalies are reviewed from the literature.Review.The detection of callosal anomalies increased rapidly with widespread use of brain imaging methods. Agenesis or dysgenesis of corpus callosum (AgCC) might be considered an accidental finding. Epileptic seizures occur in up to 89% of patients with AgCC. The causal relationship correctly is questioned. However, additional causative malformations of midline and/or telencephalic structures can be demonstrated in most seizure patients. The interruption of bilateral spread of seizure activities acts as the concept for callosotomy as epilepsy surgery. Indications are drug-resistant generalized, diffuse, or multifocal epilepsies. A resectable seizure onset zone should be excluded. Most treated patients are diagnosed as Lennox-Gastaut or Lennox-like syndrome.Conclusions.In cases with callosal abnormalities and clinical symptoms additional malformations are frequently observed, especially with seizure disorders. Callosotomy is the most effective option against drop attacks. The method probably is underused. After callosotomy a circumscript seizure focus might be unveiled and a second step of resective epilepsy surgery can be successful.

The Relationship

We report a case of mild encephalopathy with a reversible splenial lesion (MERS) associated with acute gastroenteritis caused by rotavirus (RV) infection. The patient (male, 4 years and 3 months old) was admitted to our hospital for diarrhea and afebrile seizures. Head MRI revealed a hyperintense signal in the splenium of the corpus callosum on DWI and a hypointense signal on the ADC-map. After awakening from sedation, the patient's disturbance of consciousness improved. On day 5 after admission of the illness, the patient was discharged from the hospital in a good condition. Electroencephalography on day 2 after admission was normal. On day 8 of admission, head MRI revealed that the splenial lesion had disappeared. RV antigen-positive stools suggested that RV had caused MERS. This RV genotype was considered to be G5P[6]; it may have spread to humans as a strain reassortment through substitution of porcine RV into human RV gene segments. This extremely rare genotype was detected first in Japan and is not covered by existing vaccines; this is the first sample isolated from encephalopathy patients. Few reports have investigated RV genotypes in encephalopathy; we believe that this case is valuable for studying the relationship between genotypes and clinical symptoms.

Clinical Conditions

Background: Transient splenial lesions of the corpus callosum are rare radiological findings first described in association with epilepsy, antiepileptic drugs and viral encephalitis. However, subsequently more cases were described associated with diverse clinical conditions. Case report: We describe a 13-year-old girl suffering from migraine with aura presenting with headache, right-sided hemiparesis and encephalopathy. Brain magnetic resonance imaging revealed an ovoid lesion in the splenium of the corpus callosum. The patient’s neurological symptoms resolved within 3 days without therapy and the lesion disappeared in follow up magnetic resonance images obtained 3 weeks after the onset of the symptoms. Results: Migraine with aura was considered to be the cause of the lesion. To our knowledge the present case is the first report of a pediatric patient with a diagnosis of migraine with aura presenting with hemiparesis and encephalopathy. Conclusions: A diagnosis of transient lesion of the corpus callosum should be suspected in patients with migraine with aura presenting with hemiparesis and encephalopathy. A mild course and a good prognosis might be expected in the presence of a splenial lesion of the corpus callosum.

Acute Psychosis

Psychiatric symptoms may occasionally be related to anatomic alterations of brain structures. Particularly, corpus callosum lesions seem to play a role in the change of patients’ behavior. We present a case of a sudden psychotic attack presumably due to a hemorrhagic cavernous angioma of the corpus callosum, which was surgically removed with complete resolution of symptoms. Although a developmental defect like agenesis or lipoma is present in the majority of these cases, a growing lesion of the corpus callosum can rarely be the primary cause. Since it is potentially possible to cure these patients, clinicians should be aware of this association.

Huntington’s disease is a progressive neurodegenerative disease characterized by motor, cognitive, and psychiatric symptoms. Dystonia of muscles is a characteristic feature of this condition. A case of Huntington’s disease, with orofacial dystonia, leading to severe uncontrolled biting of the lips, was referred by the Department of Neurology. Deep traumatic ulcerations were found in both upper and lower lips. A simple Essix retainer was fabricated and inserted, which acted as a barrier for the teeth from injuring the lips. The ulcers showed complete resolution in 3 to 4 weeks. The vacuum-formed retainers resulted in a good fit and resisted removal by the uncontrolled contortions of the orofacial muscles. The Essix retainer can be effectively used in improving the quality of life of patients, with Huntington’s disease, having such dystonia-related injuries to lips.

Sporadic Parkinson’S Disease

The risk of Parkinson’s disease increases with age. However, the etiology of the illness remains obscure. It appears highly likely that the neurodegenerative processes involve an array of elements that influence each other. In addition, genetic, endogenous, or exogenous toxins need to be considered as viable partners to the cellular degeneration. There is compelling evidence that indicate the key involvement of modified α-synuclein (Lewy bodies) at the very core of the pathogenesis of the disease. The accumulation of misfolded α-synuclein may be a consequence of some genetic defect or/and a failure of the protein clearance system. Importantly, α-synuclein pathology appears to be a common denominator for many cellular deleterious events such as oxidative stress, mitochondrial dysfunction, dopamine synaptic dysregulation, iron dyshomeostasis, and neuroinflammation. These factors probably employ a common apoptotic/or autophagic route in the final stages to execute cell death. The misfolded α-synuclein inclusions skillfully trigger or navigate these processes and thus amplify the dopamine neuron fatalities. Although the process of neuroinflammation may represent a secondary event, nevertheless, it executes a fundamental role in neurodegeneration. Some viral infections produce parkinsonism and exhibit similar characteristic neuropathological changes such as a modest brain dopamine deficit and α-synuclein pathology. Thus, viral infections may heighten the risk of developing PD. Alternatively, α-synuclein pathology may induce a dysfunctional immune system. Thus, sporadic Parkinson’s disease is caused by multifactorial trigger factors and metabolic disturbances, which need to be considered for the development of potential drugs in the disorder.

AbstractObjectiveTo discuss the psychiatric symptoms that are associated with CADASIL syndrome Abstract Cerebral:Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a rare type of hereditary disease involving the small cerebral vessels. The clinical symptoms are various and include recurrent ischemic strokes, migraine with aura, seizures with epilepsy, psychiatric problems such as mood disturbances, and progressive cognitive decline leading to dementia. This disease needs awareness amongst the psychiatrists even though it is discussed much more in neurology literature. Psychiatric symptoms are seen in 20–41% of patients with CADASIL syndrome (1, 2). Psychiatric symptoms are actually the initial presentation in 15% of the cases. (3) The psychiatric disturbance most reported are mood disturbances (9–41%) especially depression. Here a 42-year-old African American female was brought to the hospital emergency room after she was found wandering in the streets. Psychiatry was consulted for altered mental status. Upon evaluation by the psychiatric consult service she was only oriented to person, depressed, anxious and complaining of headaches. Initial CT scan showed marked small vessel disease and old lacunar infarcts in the basal ganglia and right corona radiata. Magnetic Resonance Imaging (MRI) of the brain showed acute infarcts in the right posterior frontal and right parietal lobes along with old infarcts. Her symptoms and findings on imaging were consistent with CADASIL syndrome. Once the diagnosis was confirmed and prior records were obtained patient was resumed on an antidepressant and anxiolytic.ConclusionThe purpose of this case report was to discuss psychiatric symptoms associated with CADASIL syndrome. Although there has been research showing a relationship between vascular disease and depression, a review of the literature suggests that there needs to be more research done to explore other psychiatric disturbances that may be seen with this syndrome. Psychiatric symptoms that are untreated can have the potential to further impact the quality of life therefore psychiatrists need to be aware of this syndrome in order to treat these patients promptly.References1 https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-017-0778-8 2 http://dx.doi.org/10.32474/OJNBD.2018.01.000101 3 https://pdfs.semanticscholar.org/47f6/5952ee3c5dcf2a61345f704914b17fa8dc0d.pdf
