    Cerebellar Lesions The cerebellum integrates sensory and other inputs to coordinate ongoing movements and participate in motor planning. The cerebellum has no direct connections to the lower motor neurons but modulates motor function through upper motor neurons. The Vermis and flocculonodular lobes regulate balance and eye movements via connections with vestibular nuclei and oculomotor system, these regions control the medial motor systems. The more lateral areas of the cerebellum control

    Cerebellar Lesions According to an article by Rhawn Joseph, Ph.D., each of the deep cerebellar nuclei maintains a semi-independent map of the human body (2000). The cerebellum is tonically active, and is presumed to exert a stabilizing influence on motor function; accordingly, it is functionally responsible for coordination and smooth fine tuning of movement, in addition to influencing timing. Not only is the cerebellum associated with motor functioning, but, importantly, also with classical

    Cerebellar Lesions Introduction: The Cerebellum The Cerebellum, accounting for approximately 25 percent of the brain, sits above the brainstem and communicates with nearly all areas of the neuroaxis. It is implicated in sensory, motor, cognitive, emotional and speech processing, display neuroplasticity, learning, and memory. (Joseph, 2000.) The cerebellum is made up of several structures, and differing regions have different functions with a primary motor component, including visual

    Cerebellar Lesions and the Neurologist What is a Neurologist? A neurologist is a medical doctor trained in the diagnosis and treatment of nervous system disorders including diseases of the brain, spinal cord, nerves and muscles (www.neurologychannel.com). Common nervous system diseases treated by neurologists include multiple sclerosis, Alzheimer’s disease, headaches, stroke or injury to the nervous system. The types of diagnostic tests employed by neurologists to detect neurological

    Cerebellar Lesions and The Neurosurgeon Modern Surgical Approaches The incorporation of computed topography into stereo tactic techniques coincided with a general interest in stereo tactic approaches to intracranial tumors. Several authors including Moser and Backlund in 1982 and Apuzzo in 1984 reported safe CT based stereo tactic tumor biopsies ofpineal region tumors. Most series of stereo tactic tumor biopsies contain a number of pineal region lesions. The reported mortality and morbidity

    Meningeal enhancement on post-contrast MRI has also been reported occasionally as well. [6] Cerebellar involvement in dengue infection is very rare. There are few previous reports describing cerebellar involvement in dengue infection. [22, 23, 24] In few cases cerebellar syndrome was result of post infectious acute disseminated demyelination. [23]. Small series from Sri Lanka reported three cases with cerebellar syndrome associated with dengue infection. Two of the patients were probably post infectious

    CENTRAL NERVOUS SYSTEM – CEREBELLAR SYSTEM Though many books include cerebellar examination as part of the motor exam, it is discussed as a separate category in view of its importance. As children with cerebellar diseases are not frequently seen in routine clinical practice, candidates tend to neglect this system in their preparation and hence find it difficult in the exam. Cerebellar assessment involves examination of the gait and co-ordination, which tests both cerebellar midline and hemispheric

    part of the neurological examination. In some instances, this area alone is given as an individual case in the exam. It is important to remember that normal stance and gait depends on intact visual, proprioceptive, corticospinal, extrapyramidal, cerebellar pathways and motor systems. There are two phases to the normal walking cycle: stance phase, when the foot is on the ground; and swing phase, when it is moving forward. While assessing gait, one should evaluate both the stance and walking (with various

    Understanding Brain Cancer The brain is the center of thought, emotion, memory, speech, and many more, and it is the most sophisticated organ in the human body. A hard skull protects the brain where it floats in a fluid called Cerebrospinal Fluid (CSF). The brain is generally set apart from the rest of the body, and functions rather differently too. Most of the brain cells are called astrocytes, and they basically support and serve the 10 billion working cells that are called neurons. These neurons

    Olivopontocerebellar Atrophy Abstract Olivopontocerebellar Atrophy(OPCA), is characterized by neuronal degeneration of the cerebellar cortex, the inferior olive, and the pons. The symptoms associated with it are primarily cerebellar ataxia with disturbances in equilibrium and gait. However, broader symptomology is usually seen with OPCA. Current research is focusing on three primary systems thought to be responsible for the etiology of OPCA. They are excitatory amino acid disturbances, oligodendroglial
