Tremor is an involuntary rhythmic muscle contraction, which causes a regular oscillation of a part of the body. Orthostatic tremor is a rare neurological movement disorder characterized by unsteadiness while standing that is relieved when sitting, walking, or lying down. Neurological examination of primary orthostatic tremor is reported to be normal. The pathophysiological mechanism of this condition is not entirely unknown. Symptoms usually start in the sixth decade. Clonazepam is widely used as a first-line medication in the treatment. A 14-year-old girl patient was admitted due to tremor activated on standing, absent while seated or lying, and improved by walking or leaning. Her brain magnetic resonance imaging and laboratory workup were normal. Tremor completely disappeared with clonazepam in 10 days. I report a case of primary orthostatic tremor in adolescence.

Disseminated cysticercosis is a rare form of cysticercosis in which the cysticerci spread throughout the body. We describe the case of a seven-year-old child with disseminated cysticercosis. He presented with a one month history of swelling of the whole body, unable to walk for one month and swelling of both eyes for 20 days. After extensive investigation from superficial musculoskeletal ultrasound B-scan of eye, brain computed tomography, brain magnetic resonance imaging (MRI), whole body MRI and pathologic biopsy, the child was diagnosed as having cysticercosis involving the brain, retina and skeletal muscles throughout the whole body.

AbstractNonketotic hyperglycemic chorea-ballism (NKHCB), also known as diabetic striato-pathy (DS) by some, is a rare complication of diabetes mellitus and uncommon in children. We report a case of a 10 11/12-year-old boy of Asian descent with uncontrolled type 1 diabetes mellitus (T1DM), Hashimoto's thyroiditis, and multiple food allergies presenting with bilateral chorea-ballism. His brain magnetic resonance imaging revealed developmental venous anomaly in right parietal lobe and right cerebellum, no focal lesions or abnormal enhancements. Choreiform movements resolved with correction of hyperglycemia. Children and adolescents with a movement disorder should be evaluated for diabetes mellitus, especially with increasing prevalence and insidious nature of T2DM associated with obesity.

✓ The purpose of this paper was to present two cases of secondary trigeminal neuralgia (TN) with an unusual origin and lesion location. In two cases TN was caused by lesions along the course of the trigeminal nerve within the pons and adjacent to the fourth ventricle. Both cases presented with typical TN. Brain magnetic resonance imaging revealed linear or wedge-shaped lesions adjacent to the fourth ventricle, extending anterolaterally and lying along the pathway of the intraaxial trigeminal fibers. The involvement of the nucleus of the spinal trigeminal tract and of the principal sensory trigeminal nucleus with segmental demyelination are suggested as possible causes for trigeminal pain in these cases. It is postulated that these lesions are the result of an old viral neuritis. The patients underwent gamma knife radiosurgery and their clinical responses have been encouraging to date.

Disease Specific

Apathy is a neuropsychiatric condition characterized by reduced motivation, initiative, and interest in daily life activities, and it is commonly reported in several neurodegenerative disorders. The study aims to investigate large-scale brain networks involved in apathy syndrome in patients with frontotemporal dementia (FTD) and Parkinson’s disease (PD) compared to a group of healthy controls (HC). The study sample includes a total of 60 subjects: 20 apathetic FTD and PD patients, 20 non apathetic FTD and PD patients, and 20 HC matched for age. Two disease-specific apathy-evaluation scales were used to measure the presence of apathy in FTD and PD patients; in the same day, a 3T brain magnetic resonance imaging (MRI) with structural and resting-state functional (fMRI) sequences was acquired. Differences in functional connectivity (FC) were assessed between apathetic and non-apathetic patients with and without primary clinical diagnosis revealed, using a whole-brain, seed-to-seed approach. A significant hypoconnectivity between apathetic patients (both FTD and PD) and HC was detected between left planum polare and both right pre- or post-central gyrus. Finally, to investigate whether such neural alterations were due to the underlying neurodegenerative pathology, we replicated the analysis by considering two independent patients’ samples (i.e., non-apathetic PD and FTD). In these groups, functional differences were no longer detected. These alterations may subtend the involvement of neural pathways implicated in a specific reduction of information/elaboration processing and motor outcome in apathetic patients.

Ordinal Logistic Regression Model

A total of 590 older adults of Amerindian ancestry living in rural Ecuador received anthropometric measurements and a brain magnetic resonance imaging to estimate the total cerebral small vessel disease (cSVD) score. A fully adjusted ordinal logistic regression model, with categories of the total cSVD score as the dependent variable, disclosed significant associations between the waist circumference, the waist-to-hip, and the waist-to-height ratios – but not the body mass index (BMI) – and the cSVD burden. Indices of abdominal obesity may better correlate with severity of cSVD than the BMI in Amerindians. Phenotypic characteristics of this population may account for these results.
