Physiological or psychological conditions, such as anxiety, anger, and fatigue, can also lead to an intention tremor known as a psychogenic tremor. Additionally, overexposure to toxic substances (e.g. alcohol dependence, mercury poisoning, etc.) can also potentially lead to intention tremors. Lastly, certain medications could also result in a ...
Cerebellum literally means little brain - and it looks like a miniature version of the brain, or cerebrum. The cerebellum coordinates movements, controls posture, balance and fine motor movement, and is involved in motor learning - like learning how to ride a bicycle. The cerebellum sits in the posterior part of the skull called the posterior ...
We’ll be talking about the hyperkinetic disorders. First up is tremor, which is an involuntary, rhythmic movement of a body part, and is the most common of all of the movement disorders. Tremors can be classified into resting, postural, and action tremors. Resting tremors develop when the affected body part is resting, and is gravity ...
Multiple sclerosis is a demyelinating disease of the central nervous system, which includes the brain and the spinal cord. Myelin is the protective sheath that surrounds the axons of neurons, allowing them to quickly send electrical impulses.
Summary. Essential tremor, also referred to as familial or benign tremor, is a neurological disorder that involves shaking of the hands, arms, vocal cords, or the head. It often begins gradually and gets worse over time. The shaking usually worsens during voluntary activities such as eating, drinking, writing, or writing.
Notes. Essential tremor. Friedreich ataxia. Neuroleptic malignant syndrome. Parkinson disease. Restless legs syndrome. This Osmosis High-Yield Note provides an overview of Movement disorders essentials. All Osmosis Notes are clearly laid-out and contain striking images, tables, and diagrams to help visual learners understand complex topics ...
Dysmetria is the inability to control the distance, speed and range of motion necessary to perform smoothly coordinated movements. It can be seen in individuals with cerebellar damage due to brain trauma, brain tumors, metabolic diseases, and demyelinating or degenerative disorders. Dysmetria can be demonstrated by clinical tests to assess ...
The cerebrum, cerebellum, and basal ganglia all help coordinate movements, so movement disorders can be traced back to these structures. Movement disorders can be broadly grouped into 2 categories, hypokinetic disorders, which cause slowness of movement, and hyperkinetic disorders, which cause excessive involuntary movement.
Summary. Wilson disease is a rare autosomal recessive genetic disorder that causes excessive accumulation of copper in various tissues of the body, particularly the liver, and brain as a result of a mutation in the ATP7B gene.
Cerebelo significa literalmente \"cerebro pequeño\", y parece una versión en miniatura del cerebro. El cerebelo coordina los movimientos, controla la postura, el equilibrio y la motricidad fina, y participa en el aprendizaje motor, como por ejemplo aprender a montar en bicicleta. Se encuentra en la parte posterior del cráneo, llamada fosa ...
