HEALTH TIPS! Too much or too less sleep can increase heart disease risk

Men who sleep less than six hours a night may be at an increased risk of cardiovascular disease compared to those who sleep between seven and eight hours, a new study suggests.

The study showed that poor quality sleep of less than six hours increases the risk of atherosclerosis by 27 per cent compared to seven to eight hours of sleep.

Atherosclerosis refers to the build-up of fats, cholesterol and other substances in and on the artery walls throughout the body.

On the other hand, women who slept more than eight hours a night had an increased risk of atherosclerosis.

“Cardiovascular disease is a major global problem and we are preventing and treating it using several approaches, including pharmaceuticals, physical activity and diet,” said Jose M. Ordovas, researcher at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) in Madrid.

“But the study emphasizes we have to include sleep as one of the weapons we use to fight heart disease — a factor we are compromising every day,” he added.

For the study, published in the Journal of the American College of Cardiology, the team included 3,974 bank employees among which all were without known heart disease and two-thirds were men.

In addition, alcohol and caffeine consumption were found to cause short and disrupted sleep.

“Many people think alcohol is a good inducer of sleep, but there’s a rebound effect. If you drink alcohol, you may wake up after a short period of sleep and have a hard time getting back to sleep. And if you do get back to sleep, it’s often a poor-quality sleep,” Ordovas said.

Lack of sleep has been known to raise the risk of cardiovascular disease by increasing heart disease risk factors such as glucose levels, blood pressure, inflammation and obesity.

Rare genetic brain disease reported, ‘Myoclonus-Dystonia’

Bangalore: A rare genetic brain disease causing a movement disorder has been reported from Mumbai where a 21-year-old patient has been diagnosed with ‘Myoclonus-Dystonia’ with facial, neck and hand shaking and jerking due to rare genetic disorder called ADCY5-related dyskinesia.

This is a rare disease with less than 400 cases reported all over the world. The disorder is known to cause abnormal involuntary tremors in the body and is usually seen in children, but this is the first time it has been reported in an Indian adult patient.

He suffered from the condition since he was 13, but these jerks were initially mild. This progressed to moderate severity over the last few years. “We were able to manage the trembling till the time they were mild. With time, the intensity increased and so did the frequency which hampered daily activities and even any work that needed concentration”, told the parents of the 21 year old.

Dr VL Ramprasad, COO, MedGenome Labs that performed the genetic testing said, “ADCY5 mutation causes abnormal involuntary movements affecting the neck, arms and face. This mutation can also lead to episodic worsening triggered by anxiety, stress or inactivity -or characteristically periods before or after sleep. We have now published this case in MDCP (Movement Disorders Clinical Practice), which is a well-known journal.”

The doctor informed that when the patient came to them he would get these movements in spells intermittently in the early years. His whole body was shaking when he was anxious or even concentrating on an activity. After initial tests the doctors were convinced that he had a rare genetic disorder and tests confirmed ADCY5 gene mutation
