Lack of sleep may cause your brain to eat itself or cause dementia

When you go without sleep for 20 to 25 hours, your performance impairment is similar to that of someone with a blood-alcohol level of 0.10 percent. At 36, 48, and 72 hours without sleep, your body and your mind begin operating in altered states that put your health, and your life, at risk.

All-night study sessions, important business deals, new babies — most people will experience a taste of sleep deprivation at some point in life. While the occasional lack of sleep may not seem like a big deal, the impact of sleep deprivation can be intense and its effects can linger. In extreme circumstances, sleep deprivation can ultimately lead to death.

Lack of sleep can cause parts of the brain’s synapses to be ‘eaten’ by other brain cells, according to a new study by researchers at the Marche Polytechnic University in Italy.  Astrocytes are a cell in the brain that clean out worn-out cells and debris. Scientists studying the brains of mice found these cells were more active when the animals had been deprived of sleep, breaking down more of the brain’s connections.

It was also discovered that microglial cells become more active after sleep deprivation. Previous research has found that chronic sleep deprivation increases so-called plaques in the brain thought to be a main cause of Alzheimer’s and other dementias.

It’s not just how long you sleep that matters. The quality of your sleep is just as important. Every night you need to go through several stages of sleep – falling peacefully into a deep sleep and periodically returning to so-called REM (Rapid Eye Movement) sleep before entering another period of deep sleep or waking up. During REM sleep,( which is when we dream) your brain is quite active, which is believed to be due to the brain consolidating recently learned information and transferring it into long-term memory. That’s one of the reasons why, we need both deep and REM sleep, because the right type of sleep, as well as the right amount of sleep, is so important for school children.



The consequences of sleep deprivation at 24 hours is comparable to the cognitive impairment of someone with a blood-alcohol content of 0.10 percent, according to a 2010 study in the International Journal of Occupational Medicine and Environmental Health. “Judgment is affected, memory is impaired, there is deterioration in decision making, and a decline in eye-hand coordination,” Cralle says. “You’re more emotional, attention is decreased, hearing is impaired, and there is an increase in your risk of death from a fatal accident.”

At 36 hours your health begins to be at risk. High levels of inflammatory markers are in the bloodstream, said Cralle, which can eventually lead to cardiovascular disease and high blood pressure. Additionally, hormones are affected — your emotions can be all over the place.

Not all instances of sleep deprivation are voluntary. Insomnia, sleep apnea, restless legs syndrome, night terrors, sleepwalking, and other problems can affect sleep. See your Doctor if you experience any sleep problems.

Heart of Gold Cop Retires From WMPolice

Taken 1986

One of West Midlands Police’s most senior black officers has retired after a law and order career stretching back more than 30 years − and has urged more members of the black community to “make a difference” by choosing police careers.

Keith Fraser − the only black Superintendent currently with the force − has spoken of his immense pride at serving the public since his first day on patrol back in 1985. In a varied career he’s gone from beat patrols in Barking, via New Scotland Yard to the West Midlands where he’s worked in child protection, crime investigation, neighbourhood policing and specialist roles like tactical firearms commander.

He said:

“The service really does need and value difference. Anyone who cares about their communities should look at joining the police… there is no point standing on the outside looking in when you could make a real difference. One of the proudest moments in my life was putting on my uniform for the first time: the look of pride on my family’s faces will never leave me. It made me feel so happy and confirmed I’d make the right decision.

“I’ve lost track of the amount of times people have come up to me in the street to shake my hand or say how ‘it’s good to see a black police officer here’ − some have literally stopped their car to get out and say thanks. People who are not white shouldn’t be such a rarity in policing.”

“I have experienced some challenges based on the colour of my skin and some racist comments − but they have been very rare occasions. There is less racism in the police than some people want to believe. I feel sometimes where we get it wrong it’s as a result of unwitting actions or lack of knowledge. The vast majority of police officers I have come into contact with are really driven with a passion and a desire to help others. Most members of the public will not see most of what officers do to help them behind-the-scenes.”

Since joining West Midlands Police in 2005, Keith has worked in Birmingham, Stourbridge, Walsall and Wolverhampton and been the force’s lead for children and young people and a victims’ champion. He’s also helped create a group aimed at preventing young people getting sucked into crime and gang activity and received several bravery commendations, including one for tackling a knifeman while he was off duty at a post office paying his car tax.

“It’s a hugely rewarding job,” added Keith.

“As a child I always had a strong desire to help others − it sounds a bit clichéd but I think it was driven by watching my mom and dad who worked hard, gave a lot to others and expected nothing in return.

“I first applied to become a police officer when I was 13-years-old. Thankfully someone from the Home Office replied with a fantastic letter of encouragement and advice for the future. The person who took the time to reply helped to keep my desire to be a cop alive.”

Keith has a big Heart of Gold – is a Trustee at Sports Birmingham – Sport Birmingham is governed by a number of Board members who bring with them a wealth of skills and knowledge. The Board’s key aims are to work with partners to increase participation in sport, physical education and active recreation, and to build clear pathways for people with sporting talent to enable them to reach their potential.

Keith is very passionate about helping young people and was delighted to be asked to Chair a charity that shares the same commitment to raising the aspirations of young people throughout the West Midlands and beyond. Is now Trustee of Employability UK – which is designed to meet the needs and expectations of students, teachers, governors, parents/carers and OFSTED. They are flexible and targeted and can be shaped to individual school needs.

#WorldSmileDay Because you are stronger now than you were yesterday

“Laugh, even when you feel too sick or too worn out or tired.
Smile, even when you’re trying not to cry and the tears are blurring your vision.
Sing, even when people stare at you and tell you your voice is crappy.
Trust, even when your heart begs you not to.
Twirl, even when your mind makes no sense of what you see.
Frolic, even when you are made fun of.
Kiss, even when others are watching.
Sleep, even when you’re afraid of what the dreams might bring.
Run, even when it feels like you can’t run any more.
And, always, remember, even when the memories pinch your heart.

Because the pain of all your experience is what makes you the person you are now. And without your experience
–you are an empty page, a blank notebook, a missing lyric. What makes you brave is your willingness to live through your terrible life and hold your head up high the next day.

So don’t live life in fear.
Because you are stronger now, after all the crap has happened, than you ever were back before it started.”
― Alysha Speer
