Currently there is no cure for dysmetria itself as it is actually a symptom of an underlying disorder. However, isoniazid and clonazepam have been used to treat dysmetria. Frenkel exercises treat dysmetria. There have also been numerous reported cases of chiropractic neurology as an effective holistic treatment for dysmetria. Cannabis has been used in trials in the U.K. and displayed some success, though it is not legal to use in some U.S. states.

Researchers now are testing different possibilities for treating dysmetria and ataxia. One opportunity for treatment is called rehearsal by eye movement. It is believed that visually guided movements require both lower- and higher-order visual functioning by first identifying a target location and then moving to acquire what is sought after. In one study, researchers used visually guided stepping which is parallel to visually guided arm movements to test this treatment. The patients suffered from saccadic dysmetria which in turn caused them to overshoot their movements 3. The patients first walked normally and were then told to twice review the area that was to be walked through 3. After rehearsal with eye movements, the patients improved their motor performance. Researchers believe that prior rehearsal with the eyes might be enough for a patient who suffers from motor dysmetria as a result of saccadic dysmetria to complete a motor task with enhanced spatial awareness.

Research has also been done for those patients who suffer from MS. Deep brain stimulation (DBS) remains a viable possibility for some MS patients though the long-term effects of this treatment are currently under review. The subjects who have undergone this treatment had no major relapse for six months and disabling motor function problems. Most subjects benefited from the implantation of the electrodes and some reported that their movement disorder was gone after surgery. However, these results are limiting at this time because of the small range of subjects who were used for the experiment and it is unknown whether this is a viable option for all MS patients who suffer from motor control problems.

"For many years, it was thought that postural and balance disorders in cerebellar ataxia were not treatable. However, the results of several recent studies suggest that rehabilitation can relieve postural disorders in patients with cerebellar ataxia...There is now moderate level evidence that rehabilitation is efficient to improve postural capacities of patients with cerebellar ataxia – particularly in patients with degenerative ataxia or multiple sclerosis. Intensive rehabilitation programs with balance and coordination exercises are necessary. Although techniques such as virtual reality, biofeedback, treadmill exercises with supported bodyweight and torso weighting appear to be of value, their specific efficacy has to be further investigated. Drugs have only been studied in degenerative ataxia, and the level of evidence is low."

One approach is that it can be ameliorated to varying degrees by means of Frenkel exercises.

One main objective of the treatment is to re-establish the physiological inhibition exerted by the cerebellar cortex over cerebellar nuclei. Research using Transcranial direct-current stimulation (TCDCS) and Transcranial magnetic stimulation (TMS) shows promising results.

Additionally, mild to moderate cerebellar ataxia may be treatable with buspirone.

It is thought that the buspirone increases the serotonin levels in the cerebellum and so decreases ataxia.

Individuals with cerebellar ataxia have full cognitive awareness: it is usually only the physical deterioration that prohibits them from participating in activities of daily living and any other relevant or desired interests. One of the most significant barriers in the lives of these individuals is dysarthria. Due to their cognitive stability, it is important that people who spend time with individuals with this disease are able to communicate as fully as possible with them. This is necessary in order to improve their day-to-day interactions.

Behavioral intervention is successful when it involves engaging knowledge of the interests and general backgrounds of individuals with cerebellar ataxia. Communication maximizing strategies are also useful, such as exaggeration of articulatory gestures, giving full attention to their responses, repeating where necessary, and slowing down speaking rate. Another intervention technique for speech is to focus on optimizing respiratory and vocal resources as well as training compensatory strategies.

These listed intervention techniques can improve quality of life in individuals with this disease and can be helpful for professionals/clinicians in the field as well as loved ones of those affected.

There is much research that needs to be conducted on CCAS. A necessity for future research is to conduct more longitudinal studies in order to determine the long-term effects of CCAS. One way this can be done is by studying cerebellar hemorrhage that occurs during infancy. This would allow CCAS to be studied over a long period to see how CCAS affects development. It may be of interest to researchers to conduct more research on children with CCAS, as the survival rate of children with tumors in the cerebellum is increasing. Hopefully future research will bring new insights on CCAS and develop better treatments.

The current treatments for CCAS focus on relieving the symptoms. One treatment is a cognitive-behavioral therapy (CBT) technique that involves making the patient aware of his or hers cognitive problems. For example, many CCAS patients struggle with multitasking. With CBT, the patient would have to be aware of this problem and focus on just one task at a time. This technique is also used to relieve some motor symptoms. In a case study with a patient who had a stroke and developed CCAS, improvements in mental function and attention were achieved through reality orientation therapy and attention process training. Reality orientation therapy consists of continually exposing the patient to stimuli of past events, such as photos. Attention process training consists of visual and auditory tasks that have been shown to improve attention. The patient struggled in applying these skills to “real-life” situations. It was the help of his family at home that significantly helped him regain his ability to perform activities of daily living. The family would motivate the patient to perform basic tasks and made a regular schedule for him to follow.

Transcranial magnetic stimulation (TMS) has also been proposed to be a possible treatment of psychiatric disorders of the cerebellum. One study used TMS on the vermis of patients with schizophrenia. After stimulation, the patients showed increased happiness, alertness and energy, and decreased sadness. Neuropsychological testing post-stimulation showed improvements in working memory, attention, and visual spatial skill. Another possible method of treatment for CCAS is doing exercises that are used to relieve the motor symptoms. These physical exercises have been shown to also help with the cognitive symptoms.

Medications that help relieve deficits in traumatic brain injuries in adults have been proposed as candidates to treat CCAS. Bromocriptine, a direct D2 agonist, has been shown to help with deficits in executive function and spatial learning abilities. Methylphendiate has been shown to help with deficits in attention and inhibition. Neither of these drugs has yet been tested on a CCAS population. It may also be that some of the symptoms of CCAS improve over time without any formal treatment. In the original report of CCAS, four patients with CCAS were re-examined one to nine months after their initial neuropsychological evaluation. Three of the patients showed improvement in deficits without any kind of formal treatment, though executive function was still found to be one standard deviation below average. In one patient, the deficits worsened over time. This patient had cerebellar atrophy and worsened in visual spatial abilities, concept formation, and verbal memory. It should be noted that none of these treatments were tested on a large enough sample to determine if they would help with the general CCAS population. Further research needs to be done on treatments for CCAS.

Ocular dysmetria is a form of dysmetria that involves the constant under- or over-shooting of the eyes when attempting to focus gaze on something.

Ocular dysmetria indicates lesions in the cerebellum, which is the brain region responsible for coordinating movement. It is a symptom of several neurological conditions including multiple sclerosis.

It is a condition that can cause symptoms similar to sea sickness.

It is very difficult to treat an intention tremor. The tremor may disappear for a while after a treatment has been administered and then return. This situation is addressed with a different treatment. First, individuals will be asked if they use any of the drugs known to cause tremors. If so, they are asked to stop taking the medication and then evaluated after some time to determine if the medication was related to the onset of the tremor. If the tremor persists, treatment that follows may include drug therapy, lifestyle changes, and more invasive forms of treatment, such as surgery and thalamic deep brain stimulation.

Intention tremors are known to be very difficult to treat with pharmacotherapy and drugs. Although there is no established pharmacological treatment for an intention tremor, several drugs have been found to have positive effects on intention tremors and are used as treatment by many health professionals. Isoniazid, buspirone hydrochloride, glutethimide, carbamazepine, clonazepam, topiramate, zofran, propranolol and primidone have all seen moderate results in treating intention tremor and can be prescribed treatments. Isoniazid inhibits γ-aminobutyric acid-aminotransferase, which the first step in enzymatic breakdown of GABA, thus increasing GABA, the major inhibitory neurotransmitter in the central nervous system. This causes a reduction in cerebellar ataxias. Another neurotransmitter targeted by drugs that has been found to alleviate intention tremors is serotonin. The agonist buspirone hydrochloride, which decreases serotonin's function in the central nervous system, has been viewed as an effective treatment of intention tremors.

Physical therapy has had great results in reducing tremors but usually does not cure them. Relaxation techniques, such as meditation, yoga, hypnosis, and biofeedback, have seen some results with tremors. Wearing wrist weights which weigh down one's hands as they make movements, masking much of the tremor, is a proven home remedy. This is not a treatment, since wearing the weights does not have any lasting effects when they are not on. However, they do help the individual cope with the tremor immediately.

A more radical treatment that is used in individuals who do not respond to drug therapy, physical therapy, or any other treatment listed above, with moderate to severe intention tremors, is surgical intervention. Deep brain stimulation and surgical lesioning of the thalamic nuclei has been found to be an effective long-term treatment with intention tremors.

Deep brain stimulation treats intention tremors but does not help related diseases or disorders such as dyssynergia and dysmetria. Deep brain stimulation involves the implantation of a device called a neurostimulator, sometimes called a 'brain pacemaker'. It sends electrical impulses to specific parts of the brain, changing brain activity in a controlled manner. In the case of an intention tremor, the thalamic nuclei is the region targeted for treatment. This form of treatment causes reversible changes and does not cause any permanent lesions. Since it is reversible, deep brain stimulation is considered fairly safe: Reduction in tremor amplitude is almost guaranteed and sometimes resolved. Some individuals with multiple sclerosis have seen sustained benefits in MS progress.

Thalamotomy is another surgical treatment where lesions of the thalamus nucleus are created to disrupt the tremor circuit. Thalamotomy has been used to treat many forms of tremors, including those that arise from trauma, multiple sclerosis, stroke, and those whose cause it unknown. This is a very invasive, high-risk treatment with many negative effects, such as multiple sclerosis worsening, cognitive dysfunction, worsening of dysarthria, and dysphagia. Immediate positive effects are seen in individuals treated with a thalamotomy procedure. However, the tremor often comes back; it is not a complete treatment. Thalamotomy is in clinical trials to determine the validity of the treatment of intention tremors with all its high risks.

In most cases, between the age of 2 and 4 oculomotor signals are present. Between the age of 2 and 8, telangiectasias appears. Usually by the age of 10 the child needs a wheel chair. Individuals with autosomal recessive cerebellum ataxia usually survive till their 20s; in some cases individuals have survived till their 40s or 50s.

Research has focused on finding a pharmacological treatment that is specific for intention tremor. Limited success has been seen in treating intention tremor with drugs effective at treating essential tremor. Clinical trials of levetiracetam, typically used to treat epilepsy, and pramipexole, used to treat resting tremor, were completed in 2009-2010 to establish their effectiveness in treating kinetic tremor. A clinical trial for riluzole, typically used to treat amyotrophic lateral sclerosis, was completed at the Sapienza University of Rome to evaluate its effectiveness of treating cerebellar ataxia and kinetic tremor.

In terms of the specific rehabilitation of visuoperceptual disorders such as Bálint's syndrome, the literature is extremely sparse. According to one study, rehabilitation training should focus on the improvement of visual scanning, the development of visually guided manual movements, and the improvement of the integration of visual elements. Very few treatment strategies have been proposed, and some of those have been criticized as being poorly developed and evaluated.

Three approaches to rehabilitation of perceptual deficits, such as those seen in Bálint's syndrome, have been identified:

1. The adaptive (functional) approach, which involves functional tasks utilising the person's strengths and abilities, helping them to compensate for problems or altering the environment to lessen their disabilities. This is the most popular approach.

2. The remedial approach, which involves restoration of the damaged CNS by training in the perceptual skills, which may be generalised across all activities of daily living. This could be achieved by tabletop activities or sensorimotor exercises.

3. The multicontext approach, which is based on the fact that learning is not automatically transferred from one situation to another. This involves practicing of a targeted strategy in a multiple environment with varied tasks and movement demands, and it incorporates self-awareness tasks.

Idebenone, an antioxidant, was recently removed from the Canadian market in 2013 due to lack of effectiveness. A Cochrane review on antioxidants and other pharmacological treatment of patients with Friedreich ataxia concluded that there is limited but not persuasive evidence of efficacy.

Nicotinamide administration on patients was associated with a sustained improvement in frataxin concentrations towards those seen in asymptomatic carriers during 8 weeks of daily dosing. The daily oral administration of 3.8 g nicotinamide resulted in a 1.5-times increase, whereas 7.5 g resulted in a doubling of frataxin protein concentration.

Autosomal recessive cerebellar ataxia type 1 (ARCA1) is a condition characterized by progressive problems with movement. Signs and symptoms of the disorder first appear in early to mid-adulthood. People with this condition initially experience impaired speech (dysarthria), problems with coordination and balance (ataxia), or both. They may also have difficulty with movements that involve judging distance or scale (dysmetria). Other features of ARCA1 include abnormal eye movements (nystagmus) and problems following the movements of objects with their eyes. The movement problems are slowly progressive, often resulting in the need for a cane, walker, or wheelchair.

Bálint's syndrome is an uncommon and incompletely understood triad of severe neuropsychological impairments: inability to perceive the visual field as a whole (simultanagnosia), difficulty in fixating the eyes (oculomotor apraxia), and inability to move the hand to a specific object by using vision (optic ataxia). It was named in 1909 for the Austro-Hungarian neurologist and psychiatrist Rezső Bálint who first identified it.

Bálint's syndrome occurs most often with an acute onset as a consequence of two or more strokes at more or less the same place in each hemisphere. Therefore, it occurs rarely. The most frequent cause of complete Bálint's syndrome is said by some to be sudden and severe hypotension, resulting in bilateral borderzone infarction in the occipito-parietal region. More rarely, cases of progressive Bálint's syndrome have been found in degenerative disorders such as Alzheimer's disease or certain other traumatic brain injuries at the border of the parietal and the occipital lobes of the brain.

Lack of awareness of this syndrome may lead to a misdiagnosis and resulting inappropriate or inadequate treatment. Therefore, clinicians should be familiar with Bálint's syndrome and its various etiologies.

Karak syndrome is a neurological degenerative disorder involving excess cerebral iron accumulation. The family who the disease was discovered in their siblings lived in Karak, a town in southern Jordan. It is characterized by ataxia, inverted feet (talipes calcaneovarus), dysarthric scanning speech with dystonic features, dystonic movement of the tongue and facial muscles and choreiform movement was present in both upper and lower limbs, being more marked in the lower limbs, along with dystonic posture of the distal feet, bradykinesia

present in both upper and lower limbs, dysmetria, dysdiadochokinesia, and intentional tremor were bilateral and symmetrical.

Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the locomotor system. In the horse, it is most commonly caused by pain, but can be due to neurologic or mechanical dysfunction. Lameness is a common veterinary problem in racehorses, sport horses, and pleasure horses. It is one of the most costly health problems for the equine industry, both monetarily for the cost of diagnosis and treatment, and for the cost of time off resulting in loss-of-use.

A detailed history is the first step of a lameness exam.

1. Age: Foals are more likely to have infectious causes of lameness (septic arthritis). Horses just starting training may be lame due to a developmental orthopedic disease, such as osteochondrosis. Older animals are more likely to experience osteoarthritis.

2. Breed: Breed-specific diseases, such as HYPP, can be ruled out. Additionally, some breeds or types are more prone to certain types of lameness.

3. Discipline: Certain lamenesses are associated with certain uses. For example, racehorses are more likely to have fatigue-related injuries such as stress fractures and injury to the flexor tendons, while western show horses are more likely to suffer from navicular syndrome and English sport horses are more likely to have osteoarthritis or injury to the suspensory ligament.

4. Past history of lameness: An old injury may be re-injured. In the case of progressive disease, such as osteoarthritis, a horse will often experience recurrent lameness that must be managed. Shifting lameness may suggest a bilateral injury or infectious cause of lameness.

5. Duration and progression the lameness: Acute injury is more common with soft tissue injury. Chronic, progressive disease is more common in cases such as osteoarthritis and navicular disease.

6. Recent changes in management: such as turn-out, exercise level, diet, or shoeing.

7. Effect of exercise on degree of lameness.

8. Any treatment implemented, including rest.

The only treatment for classic galactosemia is eliminating lactose and galactose from the diet. Even with an early diagnosis and a restricted diet, however, some individuals with galactosemia experience long-term complications such as speech difficulties, learning disabilities, neurological impairment (e.g. tremors, etc.), and ovarian failure. Symptoms have not been associated with Duarte galactosemia, and many individuals with Duarte galactosemia do not need to restrict their diet at all. However, research corroborates a previously overlooked theory that Duarte galactosemia may lead to language developmental issues in children with no clinical symptoms. Infants with classic galactosemia cannot be breast-fed due to lactose in human breast milk and are usually fed a soy-based formula.

Galactosemia is sometimes confused with lactose intolerance, but galactosemia is a more serious condition. Lactose intolerant individuals have an acquired or inherited shortage of the enzyme lactase, and experience abdominal pains after ingesting dairy products, but no long-term effects. In contrast, a galactosemic individual who consumes galactose can cause permanent damage to their bodies.

Long term complication of galactosemia includes:

- Speech deficits

- Ataxia

- Dysmetria

- Diminished bone density

- Premature ovarian failure

- Cataract

Galactose is converted into glucose by the action of three enzymes, known as the Leloir pathway. There are diseases associated with deficiencies of each of these three enzymes:
