Survival rates for those diagnosed with typical PKAN is 11.18 years with a standard deviation of 7.8 years.

Due to neuroferritinopathy’s genetic etiology, the disorder is not currently curable. Furthermore, progression of the disorder is unable to be effectively halted. Therefore current treatment focuses on managing symptoms of the disorder.

No medication is available to treat all symptoms. Botox has been shown to help with focal dystonia. The dopamine depleter Tetrabenazine shown to help with involuntary movements. Symptoms affecting movement (dystonia) have also been treated with L-Dopa, orphenadrine, benzhexol, sulpiride, diazepam, clonazepam, and deanol. Parkinsonian symptoms were not decreased by L-Dopa. Iron supplements should be avoided.

There have been no major breakthroughs in the treatment of PKAN, with most pharmacologic treatments focusing on the easing or temporary relieving of PKAN’s symptoms. Iron chelating agents have been used somewhat successfully in retarding the disorder, but they have not been a significant success.

Current research focuses on the future use of high dose pantothenate, the PANK2 enzyme substrate, in possibly alleviating symptoms as well as the further development of iron chelating agents that may be better aimed at reaching the central nervous system and working to better remove excess iron from the individual’s system.

Complications may result from the medication used to treat symptoms. Immobility from the disease can also lead to skin breakdown, respiratory infections, and blood clots, among others.

New potential treatment options being researched are Venesection (removing red blood cells), Iron chelation with deferiprone, and Coenzyme Q10 (ubiquinone).

An effective treatment has yet to be found. In many cases electrical stimulation of the globus pallidus has been shown to produce improvement of dystonia severity, however it has not been shown to delay neurodegeneration. There is often overlap in the phenotypes of the symptoms both between different NBIA disorders and between NBIA and other disorders, leading to misdiagnoses. Treatments typically treat or ameliorate the symptoms and do not address the accumulation of iron. Psychotherapy, such as dopaminergic drugs, anticholinergics, tetrabenazine, is often used to treat the symptoms but does not improve the long term outcome of the patient.

The group includes the following disorders:

- Pantothenate kinase-associated neurodegeneration (PKAN) also known as neurodegeneration with brain iron accumulation 1 (NBIA1) and Hallervorden–Spatz syndrome

- PLAN (PLA2G6-associated neurodegeneration)

- MPAN (Mitochondrial membrane protein-associated neurodegeneration)

- BPAN (Beta-propeller protein-associated neurodegeneration)

- FAHN (Fatty acid hydroxylase-associated neurodegeneration)

- Kufor–Rakeb syndrome

- Neuroferritinopathy

- Aceruloplasminemia

- Woodhouse–Sakati syndrome

- CoPAN (CoA synthase protein-associated neurodegeneration)

- Idiopathic NBIA

- Neurodegeneration with brain iron accumulation 2B (NBIA2B)

- Neurodegeneration with brain iron accumulation 3 (NBIA3)

The treatment to battle the disease chorea-acanthocytosis is completely symptomatic. For example, Botulinum toxin injections can help to control orolingual dystonia.

Deep Brain Stimulation is a treatment that has varied effects on the people suffering from the symptoms of this disease, for some it has helped in a large way and for other people it did not help whatsoever, it is more effective on specific symptoms of the disease. Patients with chorea-acanthocytosis should undergo a cardiac evaluation every 5 years to look for cardiomyopathy.

Treatment includes the use of iron chelating agents (such as desferrioxamine) to lower serum ferritin concentration, brain and liver iron stores, and to prevent progression of neurologic symptoms. This, combined with fresh-frozen human plasma (FFP) effectively in decreasing liver iron content. Repetitive use of FFP can even improve neurologic symptoms. Antioxidants such as vitamin E can be used simultaneously to prevent tissue damage to the liver and pancreas.

An average clinical profile from published studies shows that the median onset age for HDLS patients is 44.3 years with a mean disease duration of 5.8 years and mean age of death at 53.2 years. As of 2012, there have been around 15 cases identified with at least 11 sporadic cases of HDLS. HDLS cases have been located in Germany, Norway, Sweden, and the United States, showing an international distribution focusing between Northern Europe and the United States.

Through the study of numerous kindred, it was found that the disease did not occur among just males or females, but rather was evenly distributed indicative of an autosomal rather than a sex-linked genetic disorder. It was also observed that the HDLS cases did not skip generations as it would occur with a recessive inheritance, and as such has been labeled autosomal dominant.

Neurodegeneration with brain iron accumulation (NBIA) is a group of inherited neurological disorders in which iron accumulates in the basal ganglia, resulting in progressive dystonia, Parkinsonism, spasticity, optic atrophy or retinal degeneration and neuropsychiatric abnormalities. NBIA disorders have been associated with genes in synapse and lipid metabolism related pathways. Describes a group of disorders characterized by an accumulation of brain iron and the presence of axonal spheroids in the central nervous system. Iron accumulation can occur any where in the brain, with accumulation typically occurring in globus pallidus, substantia nigra, pars reticula, striatum and cerebellar dentate nuclei. Symptoms can include various movement disorders, seizures, visual disturbances, and cognitive decline, usually in combination. The known causes of NBIA disorders are mutations in genes directly involved in iron metabolism, impaired phospholipid and ceramide metabolism, lysosomal disorders, as well as mutations in genes with unknown functions. Onset can occur at different ages, from early childhood to late adulthood. Magnetic resonance imaging (MRI) is used to distinguish between the different forms of NBIA due to the accumulation of iron in different areas of the brain. Patients typically fall into two different categories: (1) early onset, rapid progression or (2) late onset, slow progression. The first type is considered to be the classic presentation, while the second type is the atypical presentation. Phenotypes of the different disorders appear to be dependent on age, i.e. amount of iron accumulation and cognitive ability.

Currently, no treatment slows the neurodegeneration in any of the neuroacanthocytosis disorders. Medication may be administered to decrease the involuntary movements produced by these syndromes. Antipsychotics are used to block dopamine, anticonvulsants treat seizures and botulinum toxin injections may control dystonia. Patients usually receive speech, occupational and physical therapies to help with the complications associated with movement. Sometimes, physicians will prescribe antidepressants for the psychological problems that accompany neuroacanthocytosis. Some success has been reported with Deep brain stimulation.

Mouthguards and other physical protective devices may be useful in preventing damage to the lips and tongue due to the orofacial chorea and dystonia typical of chorea acanthocytosis.

Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is a rare adult onset autosomal dominant disorder characterized by cerebral white matter degeneration with demyelination and axonal spheroids leading to progressive cognitive and motor dysfunction. Spheroids are axonal swellings with discontinuous or absence of myelin sheaths. It is believed that the disease arises from primary microglial dysfunction that leads to secondary disruption of axonal integrity, neuroaxonal damage, and focal axonal spheroids leading to demyelination. Spheroids in HDLS resemble to some extent those produced by shear stress in a closed head injury with damage to axons, causing them to swell due to blockage of axoplasmic transport. In addition to trauma, axonal spheroids can be found in aged brain, stroke, and in other degenerative diseases. In HDLS, it is uncertain whether demyelination occurs prior to the axonal spheroids or what triggers neurodegeneration after apparently normal brain and white matter development, although genetic deficits suggest that demyelination and axonal pathology may be secondary to microglial dysfunction. The clinical syndrome in patients with HDLS is not specific and it can be mistaken for Alzheimer's disease, frontotemporal dementia, atypical Parkinsonism, multiple sclerosis, or corticobasal degeneration.

Neurodegeneration is the progressive loss of structure or function of neurons, including death of neurons. Many neurodegenerative diseases – including amyotrophic lateral sclerosis, Parkinson's, Alzheimer's, and Huntington's – occur as a result of neurodegenerative processes. Such diseases are incurable, resulting in progressive degeneration and/or death of neuron cells. As research progresses, many similarities appear that relate these diseases to one another on a sub-cellular level. Discovering these similarities offers hope for therapeutic advances that could ameliorate many diseases simultaneously. There are many parallels between different neurodegenerative disorders including atypical protein assemblies as well as induced cell death. Neurodegeneration can be found in many different levels of neuronal circuitry ranging from molecular to systemic.

Research is underway worldwide to increase scientific understanding of these disorders as well to identify prevention and treatment methods. Known genetic mutations provide a basis for studying some of the conditions.

The process of neurodegeneration is not well understood, so the diseases that stem from it have, as yet, no cures. In the search for effective treatments (as opposed to palliative care), investigators employ animal models of disease to test potential therapeutic agents. Model organisms provide an inexpensive and relatively quick means to perform two main functions: target identification and target validation. Together, these help show the value of any specific therapeutic strategies and drugs when attempting to ameliorate disease severity. An example is the drug Dimebon (Medivation). This drug is in phase III clinical trials for use in Alzheimer's disease, and also recently finished phase II clinical trials for use in Huntington's disease. In March 2010, the results of a clinical trial phase III were released; the investigational Alzheimer's disease drug Dimebon failed in the pivotal CONNECTION trial of patients with mild-to-moderate disease. With CONCERT, the remaining Pfizer and Medivation Phase III trial for Dimebon (latrepirdine) in Alzheimer's disease failed in 2012, effectively ending the development in this indication.

In another experiment using a rat model of Alzheimer's disease, it was demonstrated that systemic administration of hypothalamic proline-rich peptide (PRP)-1 offers neuroprotective effects and can prevent neurodegeneration in hippocampus amyloid-beta 25–35. This suggests that there could be therapeutic value to PRP-1.

Protein degradation offers therapeutic options both in preventing the synthesis and degradation of irregular proteins. There is also interest in upregulating autophagy to help clear protein aggregates implicated in neurodegeneration. Both of these options involve very complex pathways that we are only beginning to understand.

The goal of immunotherapy is to enhance aspects of the immune system. Both active and passive vaccinations have been proposed for Alzheimer's disease and other conditions, however more research must be done to prove safety and efficacy in humans.

Chorea-acanthocytosis (ChAc, also called Choreoacanthocytosis), is a rare hereditary disease caused by a mutation of the gene that directs structural proteins in red blood cells. It belongs to a group of four diseases characterized under the name Neuroacanthocytosis. When a patient's blood is viewed under a microscope, some of the red blood cells appear thorny. These thorny cells are called acanthocytes.

Other effects of the disease may include epilepsy, behaviour changes, muscle degeneration, and neuronal degradation similar to Huntington's Disease. The average age of onset of symptoms is 35 years. The disease is incurable and inevitably leads to premature death.

Some more information about Chorea-acanthocytosis is that it is a very complex autosomal recessive adult-onset neurodegenerative disorder. It often shows itself as a mixed movement disorder, in which chorea, tics, dystonia and even parkinsonism may appear as a symptom.

This disease is also characterized by the presence of a few different movement disorders including chorea, dystonia etc.

Chorea-acanthocytosis is considered an autosomal recessive disorder, although a few cases with autosomal dominant inheritance have been noted.

Response to treatment is variable and the long-term and functional outcome is unknown. To provide a basis for improving the understanding of the epidemiology, genotype/phenotype correlation and outcome of these diseases their impact on the quality of life of patients, and for evaluating diagnostic and therapeutic strategies a patient registry was established by the noncommercial International Working Group on Neurotransmitter Related Disorders (iNTD).

The disease is named after Dr. Masaya Segawa, who provided an early clinical description.

Children of affected individuals are obligate carriers for aceruloplasminemia. If the CP mutations has been identified in a related individual, prenatal testing is recommended. Siblings of those affected by the disease are at a 25% of aceruloplasminemia. In asymptomatic siblings, serum concentrations of hemoglobin and hemoglobin A1c should be monitored.

To prevent the progression of symptoms of the disease, annual glucose tolerance tests beginning in early teen years to evaluate the onset of diabetes mellitus. Those at risk should avoid taking iron supplements.

Specific and accepted scientific treatment for PCA has yet to be discovered; this may be due to the rarity and variations of the disease. At times PCA patients are treated with prescriptions originally created for treatment of AD such as, cholinesterase inhibitors, Donepezil, Rivastigmine and Galantamine, and Memantine. Antidepressant drugs have also provided some positive effects.

Patients may find success with non-prescription treatments such as psychological treatments. PCA patients may find assistance in meeting with an occupational therapist or sensory team for aid in adapting to the PCA symptoms, especially for visual changes. People with PCA and their caregivers are likely to have different needs to more typical cases of Alzheimer's disease, and may benefit from specialized support groups such as the PCA Support Group based at University College London, or other groups for young people with dementia. No study to date has been definitive to provide accepted conclusive analysis on treatment options.

In terms of beta-mannosidosis treatment there is none currently, individuals that exhibit muscle weakness or seizures are treated based on the symptoms(since there's no cure)

Aging (senescence) increases vulnerability to age-associated diseases, whereas genetics determines vulnerability or resistance between species and individuals within species. Some age-related changes (like graying hair) are said to be unrelated to an increase in mortality. But some biogerontologists believe that the same underlying changes that cause graying hair also increase mortality in other organ systems and that understanding the incidence of age-associated disease will advance knowledge of the biology of senescence just as knowledge of childhood diseases advanced knowledge of human development.

Strategies for Engineered Negligible Senescence (SENS) is a research strategy which aims to repair a few "root causes" for age-related illness and degeneration, as well as develop medical procedures to periodically repair all such damage in the human body, thereby maintaining a youth-like state indefinitely. So far, the SENS programme has identified seven types of aging-related damage, and feasible solutions have been outlined for each. However, critics argue that the SENS agenda is optimistic at best, and that the aging process is too complex and little-understood for SENS to be scientific or implementable in the foreseeable future.

By age 3 about 30% of rats have had cancer, whereas by age 85 about 30% of humans have had cancer. Humans, dogs and rabbits get Alzheimer's disease, but rodents do not. Elderly rodents typically die of cancer or kidney disease, but not of cardiovascular disease. In humans, the relative incidence of cancer increases exponentially with age for most cancers, but levels off or may even decline by age 60–75 (although colon/rectal cancer continues to increase).

People with the so-called segmental progerias are vulnerable to different sets of diseases. Those with Werner's syndrome suffer from osteoporosis, cataracts and cardiovascular disease, but not neurodegeneration or Alzheimer's disease; those with Down syndrome suffer type 2 diabetes and Alzheimer's disease, but not high blood pressure, osteoporosis or cataracts. In Bloom syndrome, those afflicted most often die of cancer.

Unfortunately, cerebral atrophy is not usually preventable, however there are steps that can be taken to reduce the risks such as controlling your blood pressure, eating a healthy balanced diet including omega-3's and antioxidants, and staying active mentally, physically, and socially.

Studies have shown that PCA may be a variant of Alzheimer's disease (AD), with an emphasis on visual deficits. Although in primarily different, but sometimes overlapping, brain regions, both involve progressive neural degeneration, as shown by the loss of neurons and synapses, and the presence of neurofibrillary tangles and senile plaques in affected brain regions; this eventually leads to dementia in both diseases. PCA patients have more cortical damage and gray matter (cell body) loss in posterior regions, especially in the occipital, parietal, and temporal lobes, whereas Alzheimer’s patients typically experience more damage in the prefrontal cortex and hippocampus. PCA tends to impair working memory and anterograde memory, while leaving episodic memory intact, whereas AD patients typically have damaged episodic memory, suggesting some differences still lie in the primary areas of cortical damage.

Over time, however, atrophy in PCA patients may spread to regions commonly damaged in AD patients, leading to common AD symptoms such as deficits in memory, language, learning, and cognition. Although PCA has an earlier onset, many PCA patients have also been diagnosed with Alzheimer’s, suggesting that the degeneration has simply migrated anteriorly to other cortical brain regions.

There is no standard definition of PCA and no established diagnostic criteria, so it is not possible to know how many people have the condition. Some studies have found that about 5 percent of people diagnosed with Alzheimer’s disease have PCA. However, because PCA often goes unrecognized, the true percentage may be as high as 15 percent. Researchers and physicians are working to establish a standard definition and diagnostic criteria for PCA.

PCA may also be correlated with the diseases of Lewy body, Creutzfeldt–Jakob disease, Bálint's syndrome, and Gerstmann syndrome. In addition, PCA may result in part from mutations in the presenilin 1 gene (PSEN1).

Courses of treatment for children with is dependent upon the severity of their case. Children with OHS often receive physical and occupational therapy. They may require a feeding tube to supplement nourishment if they are not growing enough. In an attempt to improve the neurological condition (seizures) copper histidine or copper chloride injections can be given early in the child’s life.

However, copper histidine injections have been shown ineffective in studies of copper metabolic-connective tissue disorders such as OHS.
