Ataxia - Wikipedia. Ataxia is a neurological sign consisting of lack of voluntary coordination of muscle movements that includes gait abnormality. Ataxia is a non- specific clinical manifestation implying dysfunction of the parts of the nervous system that coordinate movement, such as the cerebellum. Ataxia can be limited to one side of the body, which is referred to as hemiataxia. Several possible causes exist for these patterns of neurological dysfunction. Dystaxia is a mild degree of ataxia.

A Chiari malformation, previously called an Arnold-Chiari malformation, is where the lower part of the brain pushes down into the spinal canal. Definition Vocal cord dysfunction (VCD) is a disorder that occurs when the vocal cords move toward each other when a person breathes, narrowing the airway.
Friedreich's ataxia has gait abnormality as the most commonly presented symptom. The word is from Greekα- [a negative prefix] + - τάξις [order] = "lack of order". CerebellarThe term cerebellar ataxia is used to indicate ataxia that is due to dysfunction of the cerebellum. The cerebellum is responsible for integrating a significant amount of neural information that is used to coordinate smoothly ongoing movements and to participate in motor planning. Although ataxia is not present with all cerebellar lesions, many conditions affecting the cerebellum do produce ataxia. People with cerebellar ataxia may have trouble regulating the force, range, direction, velocity and rhythm of muscle contractions. This results in a characteristic type of irregular, uncoordinated movement that can manifest itself in many possible ways, such as asthenia, asynergy, delayed reaction time, and dyschronometria. Individuals with cerebellar ataxia could also display instability of gait, difficulty with eye movements, dysarthria, dysphagia, hypotonia, dysmetria and dysdiadochokinesia. These deficits can vary depending on which cerebellar structures have been damaged, and whether the lesion is bilateral or unilateral. Learning Disabilities Adults. People with cerebellar ataxia may initially present with poor balance, which could be demonstrated as an inability to stand on one leg or perform tandem gait. As the condition progresses, walking is characterized by a widened base and high stepping, as well as staggering and lurching from side to side. Turning is also problematic and could result in falls.
As cerebellar ataxia becomes severe, great assistance and effort are needed to stand and walk.Dysarthria, an impairment with articulation, may also be present and is characterized by "scanning" speech that consists of slower rate, irregular rhythm and variable volume. There may also be slurring of speech, tremor of the voice and ataxic respiration. Cerebellar ataxia could result with incoordination of movement, particularly in the extremities. There is overshooting (or hypermetria) with finger to nose testing, and heel to shin testing; thus, dysmetria is evident. Impairments with alternating movements (dysdiadochokinesia), as well as dysrhythmia, may also be displayed.
There may also be tremor of the head and trunk (titubation) in individuals with cerebellar ataxia.It is thought that dysmetria is caused by a deficit in the control of interaction torques in multijoint motion. Interaction torques are created at an associated joint when the primary joint is moved. For example, if a movement required reaching to touch a target in front of the body, flexion at the shoulder would create a torque at the elbow, while extension of the elbow would create a torque at the wrist. These torques increase as the speed of movement increases and must be compensated and adjusted for to create coordinated movement. This may, therefore, explain decreased coordination at higher movement velocities and accelerations. Dysfunction of the vestibulocerebellum (flocculonodular lobe) impairs the balance and the control of eye movements. This presents itself with postural instability, in which the person tends to separate his/her feet upon standing, to gain a wider base and to avoid titubation (bodily oscillations tending to be forward- backward ones). The instability is therefore worsened when standing with the feet together, regardless of whether the eyes are open or closed. Adults Birthday Party Games more.
This is a negative Romberg's test, or more accurately, it denotes the individual's inability to carry out the test, because the individual feels unstable even with open eyes.Dysfunction of the spinocerebellum (vermis and associated areas near the midline) presents itself with a wide- based "drunken sailor" gait (called truncal ataxia), characterised by uncertain starts and stops, lateral deviations, and unequal steps. As a result of this gait impairment, falling is a concern in patients with ataxia. Studies examining falls in this population show that 7. Dysfunction of the cerebrocerebellum (lateral hemispheres) presents as disturbances in carrying out voluntary, planned movements by the extremities (called appendicular ataxia). These include. This could involve rapidly switching from pronation to supination of the forearm.

Chiari Malformation: A Basic Overview. What is a Chiari Malformation? Chiari malformation is a condition that causes brain tissue to settle into the spinal canal. It develops where your skull and neck (cervical spine) come together; when part of the skull is either too small or misshapen, part of the brain can settle into the foramen magnum. The foramen magnum is a large opening at the bottom of your skull. Nerves from the brain go through it and into the spinal canal, joining the spinal cord.
The brain shouldn't press through the foramen magnum; there should only be nerves in there. If the brain does press into the foramen magnum, that's a Chiari malformation. You can visualize a Chiari malformation by thinking about a funnel. The foramen magnum is the skinny part at the bottom, and above that is where the brain should rest. With a Chiari malformation, though, the brain goes into the skinny part of the funnel.
Causes. Chiari malformation can be caused by a structural problem with the brain, skull, or spinal canal. Those structural problems can be present at birth—those are congenital defects. Chiari malformation caused by structural defects is also called primary Chiari malformation; it isn't caused by any other condition. Secondary Chiari malformations are caused by something else—most often by surgery. This is very rare, but it is possible to develop a Chiari malformation after having surgery to remove a tumor in the skull/neck area. The surgeon may remove too much bone along with the tumor, allowing the brain to settle into the foramen magnum.
It's also possible to develop a more severe Chiari malformation after surgery to correct a primary Chiari malformation. During a posterior fossa decompression, the surgeon may remove too much bone, making it possible for the brain to settle further into the spinal canal. Again: this is very rare, but it is a possible complication of Chiari malformation surgery, one you should review with your surgeon. Types. There are four types of Chiari malformations, categorized by how much of the brain is protruding into the spinal canal. Type I: This is the adult version of Chiari malformation, and it's also the most common. It's generally first noticed during adolescence or adulthood, and often, it's discovered during an examination for something else—most people don't realize that they have Chiari malformation, unless the symptoms are quite severe. In Type I Chiari malformation, part of the brain settles into the foramen magnum—the cerebellar tonsils, to be exact, is the part going into the foramen magnum.
Type II: This is one of the pediatric version of Chiari malformation. More brain tissue pushes through the foramen magnum in Type II: the cerebellar tonsils and a portion of the brainstem protrude. Because more tissue is protruding, the symptoms are more severe with Type II than with Type I. Also, Type II always involves myelomeningocele, a form of spina bifida. With myelomeningocele, the vertebrae and spinal canal don't close correctly before birth, so the spinal cord isn't protected.
Type II is called Arnold- Chiari malformation. Type III: This is also a form that affects children, and it's more severe than Types I or II. Scarlatine Symptomes Adultes more. In it, a significant portion of the brain—the cerebellum—and the brainstem push all the way through the foramen magnum and into the spinal canal. Type IV: This is the most severe form of Chiari malformation. In Type IV, the brain doesn't develop as it should. Symptoms A Chiari malformation can disrupt the flow of cerebrospinal fluid (CSF). CSF is necessary to protect your brain and spinal cord, and if it can't flow normally, then it's more difficult for your brain and spinal cord to send and receive nerve messages.
The pressure caused by parts of the brain pushing through the foramen magnum can also cause nerve problems. As you can tell, the majority of Chiari malformation symptoms relate to neurological problems. The symptoms do vary based on the type and severity, but the most common symptom is a headache.
People with a Chiari malformation generally have headaches in the occipital region of the brain; that's the back of your head, right where you skull joins with your cervical spine (neck). These headaches are generally aggravated by particular positions and actions, including tilting your head back and coughing. Some other typical symptoms include: weaknessbalance problemsdifficulty with fine motor skills (e. For some patients, symptoms can come and go because they're dependent upon how much CSF has built up. Patients with Type I Chiari malformation may not have any symptoms—it all depends on the severity of the condition.
Diagnosis The best way to diagnose Chiari malformation is with a magnetic resonance imaging test—an MRI. The MRI will show the doctor the various parts of your brain, skull, spinal cord, and spinal canal; he or she will be able to see any abnormalities that could point to Chiari malformation.
