THURSDAY, Could 23, 2019 (HealthDay Information) — Scuffling with bipolar dysfunction is difficult sufficient, however now a brand new research from Taiwan suggests these sufferers are seven instances extra more likely to develop Parkinson’s illness.
However U.S. specialists cautioned that absolutely the threat of growing Parkinson’s — an incurable motion illness — remains to be very low for these with the temper dysfunction.
“I wasn’t shocked [by the study’s findings], as a result of comparable problems like main melancholy and anxiousness dysfunction convey an identical elevated threat of Parkinson’s later in life,” stated Dr. Gregory Pontone, director of the Parkinson’s illness analysis heart at Johns Hopkins Medication in Baltimore.
“This provides you two causes to deal with bipolar dysfunction aggressively,” he added.

For the research, researchers led by Dr. Mu-Hong Chen of Taipei Veterans Common Hospital, reviewed well being data for 56,000 individuals in Taiwan who have been recognized with bipolar dysfunction between 2001 and 2009. They have been in comparison with 225,000 individuals with no historical past of bipolar or Parkinson’s. Each teams have been tracked till late 2011.
Through the research interval, 372 individuals with bipolar dysfunction — or 0.7% — developed Parkinson’s. This in comparison with 222 — or 0.1% — of those that did not have bipolar dysfunction.
These with bipolar who developed Parkinson’s have been 9 years youthful — common age 64 — than others who additionally developed Parkinson’s, the research discovered.
“If you say there’s seven instances the danger, it will get scary. However it’s nonetheless only a few [bipolar] sufferers who get Parkinson’s,” stated Dr. Justin Martello, who reviewed the findings. He is a neurologist specializing in motion problems and Parkinson’s illness at Christiana Care Well being System in Wilmington, Del.
Martello identified that whereas the research was giant, it was restricted by together with solely individuals in Taiwan.
“We do not understand how this is able to apply extra globally or broadly,” Martello stated. “I believe it is extra attention-grabbing for physicians to know this and be extra conscious of the affiliation.”
The research was printed on-line Could 22 within the journal Neurology.
Pontone, who cowrote an accompanying editorial, and Martello stated scientists have many theories — nonetheless unproven — about how bipolar dysfunction may be linked to the event of Parkinson’s.
“A depressive or manic episode might do one thing to the mind that renders it extra susceptible” to Parkinson’s over time, Pontone stated.
And Martello famous that many drugs used to deal with bipolar dysfunction can set off Parkinson’s-like signs.
Many specialists suppose Parkinson’s is energetic years or many years earlier than motion issues present up, and temper problems comparable to bipolar may very well be an early symptom of Parkinson’s, Pontone and Martello stated.
Far more analysis remains to be wanted, they agreed.
“We undoubtedly have to look extra at a worldwide inhabitants,” Martello stated. “The researchers right here did comply with sufferers for 10 years, but it surely must be prolonged longer to see what number of of those sufferers convert to Parkinson’s down the highway.”
