MedlinePlus : ⁴³ What is progressive supranuclear palsy (PSP)? Progressive supranuclear palsy (PSP) is a rare brain disease. It happens because of damage to nerve cells in the brain. PSP affects your movement, including control of your walking and balance. It also affects your thinking and eye movement. PSP is progressive, which means that it gets worse over time. Who gets progressive supranuclear palsy (PSP)? PSP usually affects people over 60, but in some cases it can start earlier. It is more common in men. What causes progressive supranuclear palsy (PSP)? Researchers don't know what causes most cases of PSP. In rare cases, the cause is a mutation in a certain gene. One sign of PSP is abnormal clumps of tau in nerve cells in the brain. Tau is a protein in your nervous system, including in nerve cells. Some other diseases also cause a buildup of tau in the brain, including Alzheimer's disease. What are the symptoms of progressive supranuclear palsy (PSP)? Symptoms are very different in each person, but they may include A loss of balance while walking. This is often the first symptom. Speech problems Trouble swallowing A blurring of vision and problems controlling eye movement Changes in mood and behavior, including depression and apathy (a loss of interest and enthusiasm) Mild dementia How is progressive supranuclear palsy (PSP0 diagnosed? There is no specific test for PSP. It can be difficult to diagnose, because the symptoms are similar to other diseases such as Parkinson's disease and Alzheimer's disease. To make a diagnosis, your health care provider will take your medical history and do physical and neurological exams. You may have an MRI or other imaging tests. What are the treatments for progressive supranuclear palsy (PSP)? There is currently no effective treatment for PSP. Medicines may reduce some symptoms. Some non-drug treatments, such as walking aids and special glasses, may also help. People with severe swallowing problems may need gastrostomy. This is a surgery to insert a feeding tube into the stomach. PSP gets worse over time. Many people become severely disabled within three to five years after getting it. PSP isn't life-threatening on its own. It can still be be dangerous, because it increases your risk of pneumonia, choking from swallowing problems, and injuries from falling. But with good attention to medical and nutritional needs, many people with PSP can live 10 or more years after the first symptoms of the disease.

MalaCards based summary : Supranuclear Palsy, Progressive, 1, also known as progressive supranuclear palsy, is related to frontotemporal lobar degeneration with tdp43 inclusions, grn-related and semantic dementia, and has symptoms including seizures, tremor and photophobia. An important gene associated with Supranuclear Palsy, Progressive, 1 is MAPT (Microtubule Associated Protein Tau), and among its related pathways/superpathways are Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins. and Neuroscience. Affiliated tissues include brain, eye and testes, and related phenotypes are depressivity and tremor

Disease Ontology : ¹² A movement disease characterized by serious and progressive problems with control of gait and balance, along with complex eye movement and thinking problems. It involves gradual deterioration and death of specific volumes of the brain.

Genetics Home Reference : ²⁵ Progressive supranuclear palsy is a brain disorder that affects movement, vision, speech, and thinking ability (cognition). The signs and symptoms of this disorder usually become apparent in mid- to late adulthood, most often in a person's 60s. Most people with progressive supranuclear palsy survive 5 to 9 years after the disease first appears, although a few affected individuals have lived for more than a decade.

NIH Rare Diseases : ⁵³ Progressive supranuclear palsy (PSP) is a degenerative neurologic disease due to damage to nerve cells in the brain. Signs and symptoms vary but may include loss of balance; blurring of vision; problems controlling eye movement; changes in mood, behavior and judgment; cognitive decline; and slowing and slurred speech. PSP is often misdiagnosed as Parkinson disease due to similar symptoms. Onset is usually after age 60 but may occur earlier. Most cases of PSP appear to be sporadic, but familial cases have been reported. Some cases have been found to be caused by a mutation in the MAPT gene, and other genetic factors are being studied. There is currently no effective treatment for PSP, and symptoms usually do not respond to medications. Research regarding potential treatments is ongoing.

OMIM : ⁵⁷ Progressive supranuclear palsy (PSP) is the second most frequent cause of degenerative parkinsonism. In addition to parkinsonism, the clinical symptoms include early postural instability, supranuclear gaze palsy, and cognitive decline. Neuropathologically, the disorder is characterized by abundant neurofibrillary tangles, which differ in both distribution and composition from those associated with Alzheimer disease. In progressive supranuclear palsy, the tangles are primarily localized to subcortical regions and are found in both neurons and glia, whereas in Alzheimer disease they are more widespread, largely cortical, and limited to neurons. They also have different characteristics at the ultrastructural level (Baker et al., 1999). Kertesz (2003) suggested the term 'Pick complex' to represent the overlapping syndromes of frontotemporal dementia (FTD; 600274), primary progressive aphasia (PPA), corticobasal degeneration (CBD), progressive supranuclear palsy, and FTD with motor neuron disease. He noted that frontotemporal dementia may also be referred to as 'clinical Pick disease,' and that the term 'Pick disease' (172700) should be restricted to the pathologic finding of Pick bodies.

NINDS : ⁵⁴ Progressive supranuclear palsy (PSP) is a rare brain disorder that causes serious and progressive problems with control of gait and balance, along with complex eye movement and thinking problems. One of the classic signs of the disease is an inability to aim the eyes properly, which occurs because of lesions in the area of the brain that coordinates eye movements. Some individuals describe this effect as a blurring. Affected individuals often show alterations of mood and behavior, including depression and apathy as well as progressive mild dementia. The disorder's long name indicates that the disease begins slowly and continues to get worse (progressive), and causes weakness (palsy) by damaging certain parts of the brain above pea-sized structures called nuclei that control eye movements (supranuclear). PSP was first described as a distinct disorder in 1964, when three scientists published a paper that distinguished the condition from Parkinson's disease. It is sometimes referred to as Steele-Richardson-Olszewski syndrome, reflecting the combined names of the scientists who defined the disorder. Although PSP gets progressively worse, no one dies from PSP itself.

UniProtKB/Swiss-Prot : ⁷⁵ Progressive supranuclear palsy 1: Characterized by akinetic-rigid syndrome, supranuclear gaze palsy, pyramidal tract dysfunction, pseudobulbar signs and cognitive capacities deterioration. Neurofibrillary tangles and gliosis but no amyloid plaques are found in diseased brains. Most cases appear to be sporadic, with a significant association with a common haplotype including the MAPT gene and the flanking regions. Familial cases show an autosomal dominant pattern of transmission with incomplete penetrance; genetic analysis of a few cases showed the occurrence of tau mutations, including a deletion of Asn-613.
