Researchers have studying the symptoms of Parkinson’s disease for a long time. This degenerative neurological disorder affects a person’s sensory-motor functions including thinking, mood and memory.
Loss of control over body movements and tremors in limbs are other signs of the disease.
A recent study on old men shows that the symptoms of Parkinson’s disease can be identified early in life.
According to experts, frequent nightmares can be an early sign of Parkinson’s disease.
Association between distressing dreams and this neurological disorder have long in place.
This study is the first one to investigate this link.
The study involve 3,818 old men who show typical brain functioning over 12 years.
Researchers found that the men who experience frequent nightmares were twice as likely to develop Parkinson’s.
Much of the diagnosis for this study occurred in the first five years of the study.
According to the study publish in EClinicalMedicine, elder adults can be screen for the disease by asking them about the content of their dreams.
This could help in the early diagnosis of the disease.
Usually, Parkinson’s is detect only after 60% to 80% of dopamine-releasing neurons in the brain stem are damage.
Neurologist Abidemi Otaiku from the University of Birmingham in the UK said :
“Although it can be really beneficial to diagnose Parkinson’s disease early, there are very few risk indicators and many of these require expensive hospital tests or are very common and non-specific, such as diabetes.”
Further research in this direction is require to ascertain whether or not the study stands its ground.
According to a report, almost a quarter of Parkinson’s patients report having frequent nightmares.
Parkinson’s patients are also more likely to suffer from rapid eye movement sleep disorders, which may lead to a physical reenactment of dreams during sleep.
It was also noted during the research that men are more likely to face frequent nightmares than women as a symptom of Parkinson’s.
A hypothesis is that the onset of frequent nightmares at a later stage in life is an early sign of neurodegeneration in some men.
