Frequent bad dreams and nightmares in adults have been linked to developing Parkinson's disease in later life, a study suggests.
Studies in the past have shown that older people who have Parkinson’s disease are quite likely to experience frequent bad dreams or nightmares.
Experts from the University of Birmingham now think there is evidence that regular bad dreams could be an early warning sign for developing the condition.
“While we need to carry out further research in this area, identifying the significance of bad dreams and nightmares could indicate that individuals who experience changes to their dreams in older age, without any obvious trigger, should seek medical advice,” said lead author Dr Abidemi Otaku, from the university’s Centre for Human Brain Health.
The research used data from 3,818 men aged 67 years or over gathered in the US Osteoporotic Fractures in Men Study.
None of the men had Parkinson’s at the start of the research and were asked about the frequency of distressing dreams.
People reporting bad dreams at least once a week were consulted at the end of the study to see whether they were more likely to have Parkinson’s disease diagnosed.
During a seven-year follow-up, 91 cases of Parkinson’s were diagnosed, most within the first five years of the research.
Those men with frequent bad dreams during the first five years were more than three times as likely to develop Parkinson’s.
Experts now plan to use electroencephalography (EEG) to look at the biological reasons for dream changes.
They will also look at extending the research to larger groups of people of both sexes and different backgrounds, and to other neurodegenerative diseases such as Alzheimer’s.
“We know that many people with Parkinson’s experience sleep and night-time problems," said Dr Katherine Fletcher, research communications manager at Parkinson’s UK.
“While they can be experienced at any stage, research has often focused on those symptoms that may appear in the early stages of the condition, before diagnosis, as they may help us to predict who will develop Parkinson’s in the future.
“Previous research has shown that one particular sleep problem, known as rapid eye movement (REM) sleep disorder where dreams are acted out, has been linked to a higher risk of Parkinson’s.
“It is estimated that over 70 per cent of those with REM sleep disorder will go on to develop the condition, although having this disorder alone is not enough to predict a future diagnosis.
“Previous studies have also shown that the dreams of people with Parkinson’s can include more aggressive content, being overall more vivid and nightmarish, than those of people without the condition.
"There is also evidence that bad dreams might be associated with later cognitive decline.
“This new study provides further evidence that changes to sleep might be an early sign of Parkinson’s, in this case linking bad dreams to increased risk of people going on to develop the condition.
“It will be interesting to see how this research progresses when researchers begin to unpick the biological changes that are causing these changes to dream content, and how this links to the progression of neurological conditions such as Parkinson’s.
“The more that is known about the earliest signs of the condition and how the brain might be changing, the closer research will get to better treatments and a cure.
“This is of vital importance to the estimated 145,000 people currently diagnosed with Parkinson’s in the UK.”
The study was published by eClinicalMedicine.

Four motivational quotes from Alicia's Dubai talk
“The only thing we need is to know that we have faith. Faith and hope in our own dreams. The belief that, when we keep going we’re going to find our way. That’s all we got.”
“Sometimes we try so hard to keep things inside. We try so hard to pretend it’s not really bothering us. In some ways, that hurts us more. You don’t realise how dishonest you are with yourself sometimes, but I realised that if I spoke it, I could let it go.”
“One good thing is to know you’re not the only one going through it. You’re not the only one trying to find your way, trying to find yourself, trying to find amazing energy, trying to find a light. Show all of yourself. Show every nuance. All of your magic. All of your colours. Be true to that. You can be unafraid.”
“It’s time to stop holding back. It’s time to do it on your terms. It’s time to shine in the most unbelievable way. It’s time to let go of negativity and find your tribe, find those people that lift you up, because everybody else is just in your way.”

Other ways to buy used products in the UAE
UAE insurance firm Al Wathba National Insurance Company (AWNIC) last year launched an e-commerce website with a facility enabling users to buy car wrecks.
Bidders and potential buyers register on the online salvage car auction portal to view vehicles, review condition reports, or arrange physical surveys, and then start bidding for motors they plan to restore or harvest for parts.
Physical salvage car auctions are a common method for insurers around the world to move on heavily damaged vehicles, but AWNIC is one of the few UAE insurers to offer such services online.
For cars and less sizeable items such as bicycles and furniture, Dubizzle is arguably the best-known marketplace for pre-loved.
Founded in 2005, in recent years it has been joined by a plethora of Facebook community pages for shifting used goods, including Abu Dhabi Marketplace, Flea Market UAE and Arabian Ranches Souq Market while sites such as The Luxury Closet and Riot deal largely in second-hand fashion.
At the high-end of the pre-used spectrum, resellers such as Timepiece360.ae, WatchBox Middle East and Watches Market Dubai deal in authenticated second-hand luxury timepieces from brands such as Rolex, Hublot and Tag Heuer, with a warranty.

What drives subscription retailing?
Once the domain of newspaper home deliveries, subscription model retailing has combined with e-commerce to permeate myriad products and services.
The concept has grown tremendously around the world and is forecast to thrive further, according to UnivDatos Market Insights’ report on recent and predicted trends in the sector.
The global subscription e-commerce market was valued at $13.2 billion (Dh48.5bn) in 2018. It is forecast to touch $478.2bn in 2025, and include the entertainment, fitness, food, cosmetics, baby care and fashion sectors.
The report says subscription-based services currently constitute “a small trend within e-commerce”. The US hosts almost 70 per cent of recurring plan firms, including leaders Dollar Shave Club, Hello Fresh and Netflix. Walmart and Sephora are among longer established retailers entering the space.
UnivDatos cites younger and affluent urbanites as prime subscription targets, with women currently the largest share of end-users.
That’s expected to remain unchanged until 2025, when women will represent a $246.6bn market share, owing to increasing numbers of start-ups targeting women.
Personal care and beauty occupy the largest chunk of the worldwide subscription e-commerce market, with changing lifestyles, work schedules, customisation and convenience among the chief future drivers.
