conclusion our results concerning cranium morphometry support the theory that hypoplastic posterior cranial fossa due to mesodermal insufficiency may play a role in the etiology of tonsillar herniation. results in individuals with tonsillar herniation, while the front-back diameter of the foramen magnum, the cerebellum height, and the sagittal diameter of the cerebellum increased, the maximum c...

Posttraumatic cerebral infarction is a rare complication and is an indicator of poor clinical outcome of head-trauma in spite of appropriate medical and surgical interventions. Cerebellar infarction following head trauma is also very rare and only a few reported cases are available in literatures. A 2-year-old child sustained head injury in a car accident and underwent surgery because of cerebr...

Background: The cerebellum is the most important portion of the brain, which audits our acts and establishes balance. Symptoms from a cerebellar stroke happen suddenly. In addition to specific cerebellar signs and symptoms, other common symptoms of a cerebral stroke include dizziness, headache, nausea, vomiting, double vision, tremor, and vertigo. These symptoms can be confused with other situa...

Magnetic resonance imaging (MRI) research in identifying altered brain structure and function in ataxia-telangiectasia, an autosomal recessive neurodegenerative disorder, is limited. Diffusion-weighted MRI were obtained from 11 ataxia telangiectasia patients (age range, 7-22 years; mean, 12 years) and 11 typically developing age-matched participants (age range, 8-23 years; mean, 13 years). Gray...

Multiple system atrophy (MSA) is a neurodegenerative disease not only affecting the basal ganglia, brainstem, cerebellum, and intermediolateral cell columns of the spinal cord but also the cerebral cortex. Clinically, cerebellar (MSA-C) and parkinsonian variants of MSA (MSA-P) are distinguished. We investigated 14 MSA patients (10 MSA-C, 4 MSA-P, men: 7, women: 7; age: 61.1 ± 3.3 years) and 14 ...

Recent research indicates that physiotherapy can improve motor performance of patients with cerebellar degeneration. Given the known contributions of the cerebellum to motor learning, it remains unclear whether such observable changes in performance are mediated by the cerebellum or cerebral brain areas involved in motor control and learning. The current study addressed this question by assessi...

Brain magnetic resonance images (MRI) of 104 healthy children and adolescents, age 4-18, showed significant effects of age and gender on brain morphometry. Males had larger cerebral (9%) and cerebellar (8%) volumes (P < 0.0001 and P = 0.008, respectively), which remained significant even after correction for height and weight. After adjusting for cerebral size, the putamen and globus pallidus r...

Spinocerebellar ataxia type 17 (SCA17) is a rare autosomal dominant neurodegenerative disorder characterized by progressive cerebellar ataxia but also a broad spectrum of other neuropsychiatric signs. As anatomical and structural studies have shown severe cerebellar atrophy in SCA17 and a differentiation of the human cerebellum into an anterior sensorimotor and posterior cognitive/emotional par...
