Dopaminergic drugs Dopaminergic drugs are commonly used in the early stages of the hypokinesia to treat patients. With increased intake, though, they can become ineffective because of the development of noradrenergic lesions. While initially the dopaminergic drugs may be effective, these noradrenergic lesions are associated with hypokinesic gait disorder development later on. Some Parkinson's patients are unable to move during sleep, prompting the diagnosis of "nocturnal hypokinesia". Physicians have experienced success treating this sleep disorder with slow-release or night-time dopaminergic drugs, and in some cases, continuous stimulation by the dopamine agonist rotigotine. Despite improved mobility during sleep, many Parkinson's patients report an extremely uncomfortable sleeping experience even after dopaminergic treatments. Deep brain stimulation Once the reaction to dopaminergic drugs begins to fluctuate in Parkinson's patients, deep brain stimulation (DBS) of the subthalamic nucleus and internal globus pallidus is often used to treat hypokinesia. DBS, like dopaminergic drugs, initially provides relief, but chronic use causes worse hypokinesia and freezing of gait. Lower-frequency DBS in irregular patterns has been shown to be more effective and less detrimental in treatment. Parkinson surgery Posteroventral pallidotomy (PVP) is a specific kind of DBS that destroys a small part of the globus pallidus by scarring the neural tissue, reducing brain activity and therefore tremors and rigidity. PVP is suspected to recalibrate basal ganglia activity in the thalamocortical pathway. PVP in the dominant hemisphere has been reported to disrupt executive function verbal processing abilities, and bilateral PVP may disturb processes of focused attention. Many akinesia patients also form a linguistic akinesia in which their ability to produce verbal movements mirrors their physical akinesia symptoms, especially after unsuccessful PVP. Patients are usually able to maintain normal levels of fluency, but often stop midsentence, unable to remember or produce a desired word. According to a study of Parkinson's patients with articulatory hypokinesia, subjects with faster rates of speech experienced more problems trying to produce conversational language than those who normally spoke at slower rates. Methylphenidate Methylphenidate, commonly used to treat ADHD, has been used in conjunction with levodopa to treat hypokinesia in the short term. The two work together to increase dopamine levels in the striatum and prefrontal cortex. Methylphenidate mainly inhibits dopamine and noradrenaline reuptake by blocking presynaptic transporters, and levodopa increases the amount of dopamine, generally improving hypokinesic gait. Some patients, however, have adverse reactions of nausea and headache to the treatment and the long-term effects of the drug treatment still need to be assessed. Stem cells New treatments include increasing the number of dopamine cells by transplanting stem cells into the basal ganglia or stimulating endogenous stem cell production and movement to the basal ganglia. The successful integration of stem cells can relieve hypokinetic symptoms and decrease the necessary dose of dopaminergic drugs. However, a variety of complications, including possible tumor formation, inappropriate cell migration, rejection of cells by the immune system, and cerebral hemorrhage are possible, causing many physicians to believe the risks outweigh the possible benefits. NOP receptor antagonists Another treatment, still in an experimental stage, is the administration of nociception FQ peptide (NOP) receptor antagonists. This treatment has been shown to reduce hypokinesia in animal studies when increasing nociception FQ in the substantia nigra and subthalamic nucleus. Low doses can be taken with dopaminergic treatment to decrease the amount of L-dopa needed, which can reduce its long-term side effects and improve motor performance. Dance therapy Dance therapy has also been shown to reduce hypokinesic movements and rigidity, though targeted more at the muscular aspects of the disorder than the neural activity.
