ABBV-951, Levodopa as Infusion, Seen as Similar to Intestinal Gel

ABBV-951, a continuous infusion formulation of levodopa/carbidopa, brought comparable levels of levodopa into the bloodstream of healthy volunteers as surgically implanted levodopa-carbidopa intestinal gel (LCIG), a Phase 1 study confirmed. Because the delivery of doses can be tailored to a patient’s needs, this alternative form of delivery — a portable…

Better Exercise Habits May Be Matter of Class Availability, Study Finds

Offering more weekly exercise classes at a higher intensity over a wider geographical area may help to instill  better exercise habits in people with Parkinson’s disease, a study suggested.

Finger Tapping on Smartphone May Measure Parkinson’s Severity

Finger tapping data from Parkinson’s patients using smartphone screens were linked with disease severity in a large-scale analysis that used standard assessment methods. Given that current Parkinson’s severity measurements are based on clinical observations by trained movement disorder specialists, these findings suggest that approaches such as finger tapping analyses…

Aripiprazole at Low Dose Eases Parkinson’s Psychosis, If Tolerable

A low daily dose of aripiprazole, an antipsychotic therapy, significantly eased hallucinations and delusions in people with Parkinson’s disease and psychosis treated in a small, open-label study. Because one-third of the trial’s participants discontinued treatment due to a worsening of disease symptoms, patients using aripiprazole should be monitored closely for tolerability,…

Analyzing Finger Taps, Voice on Cellphone May Help in Diagnosis

Collecting finger tapping, voice, and walking data on a smartphone to be digitally processed by deep machine learning tools can accurately distinguish between people with and without Parkinson’s disease, a study of more than 7,000 people reported. This approach, known integrative digital biomarkers, may help to diagnose the disease…
