People with age-related macular degeneration, an eye disease that blurs central vision, may have a higher risk of developing Parkinson’s disease, a Taiwanese population‐based retrospective study suggests. The study, ‘Increased risk of Parkinson’s disease among patients with age-related macular degeneration,” was published in the journal BMC Ophthalmology. Age-related…

A new molecule — a peptide tweaked by scientists in the laboratory — has the potential to prevent the misfolding and toxic aggregation, or clumping, of misfolded alpha-synuclein protein, a hallmark of Parkinson’s disease, a study shows. This study, supported by funds from Alzheimer’s Research U.K., paves the…

Low oxygen levels during sleep and while exercising — resulting in poor endurance — are very common among Parkinson’s disease patients, despite dopaminergic treatment, an Italian study suggests. The findings indicate a need for combining motor and respiratory rehabilitation, particularly for patients with severe Parkinson’s, who show the lowest…

The cerebrospinal fluid, which surrounds the brain and spinal cord, of people with moderately severe Parkinson’s disease shows evidence that damage to blood vessels meant to protect the brain may be a key driver of disease progression, a study based on findings in a Phase 2 trial reported. This…

Supernus Pharmaceuticals’ portfolio of Parkinson’s disease therapies now includes Gocovri (amantadine) and Osmolex ER (amantadine hydrochloride), with the company’s acquisition of Adamas Pharmaceuticals now complete. “Adamas fits squarely within our corporate development strategy, adding a late-stage commercial product with significant revenue,” Jack Khattar, president and CEO of Supernus…

Cala Health has raised $77 million that will support further innovations of the company’s expertise — bioelectronic medicine — to explore conditions beyond essential tremor, including Parkinson’s disease and other neurological conditions. The funding also will help expand patient access to the company’s devices, which includes Cala Trio, a…

Two scientists at Yale University were awarded $2 million from the Michael J. Fox Foundation to conduct the first clinical trial investigating the use of ketamine — a powerful anesthetic — as a treatment for depression in people with Parkinson’s disease. The study will be led by Sophie…

An oral candidate therapy for Parkinson’s disease called GT-02287 lowered the levels of alpha-synuclein accumulation and inflammation, and lessened behavioral deficits in animal models of the disease. “We are working diligently to advance this breakthrough compound to the clinic and bring it one step closer to meeting the currently unaddressed needs…

Fascinate Therapeutics plans to launch a Phase 2 clinical trial into the safety and early efficacy of KM-819 as a potential therapy for Parkinson’s disease. This follows the approval by the U.S. Food and Drug Administration of Fascinate’s request for such a trial, in the form of an investigational new…

The American Academy of Neurology (AAN) has issued a new group of guidelines designed to aid clinicians in prescribing the most effective and appropriate dopaminergic medications — those that increase or mimic dopamine — to patients in the early stages of Parkinson’s disease. The new guidelines, endorsed by…
