Can’t Sleep At Night? Your Brain May Be Abnormal

September 29, 2017

Insomnia is nothing but unhealthy sleeping habits. It can be caused by either psychiatric or medical conditions.  There are various medical conditions which can lead to insomnia. Few examples are as below:

  1. Sinus allergies
  2. Arthritis
  3. Asthma
  4. Lower body pain

Medicines which usually we take for cold, fever, body ache, high blood pressure can also trouble in sleeping.  A recent study has come up that the people who suffer from insomnia is linked somewhere to their brain. Such people are more likely to have damaged brain. Insomnia itself has levels.  There are some chronic physical conditions which can be a big obstacle why you cannot sleep at nights?

Diabetes: It is a very common disease marked by elevated levels of blood glucose or sugar. It basically occurs only when our cells are not able to respond appropriately to insulin. Such people often face sleeping problems due to several factors. Some of them can be regular night sweats, frequent requirement to urinate or low blood sugar.

Heart Failure: This is a condition which is characterized by a gradual decline in their heart’s ability to pump or maybe circulate blood adequately. It can even cause damage to our lungs and tissues by causing fluid to build up inside them. Such patients sometimes cannot take proper sleeps because they feel short of breath because of the extra fluid present inside the lungs while they are lying down on the bed. Their breath ceases in the middle of night and all they feel is a stroke. Men with heart failure frequently have obstructive sleep apnea—breathing disorders characterized by multiple nighttime awakenings—which can disrupt sleep, cause daytime sleepiness, and worsen heart failure. In people with coronary artery disease, the natural fluctuations in circadian rhythms may trigger angina (chest pain), arrhythmia (irregular heartbeat), or even heart attack while asleep.

The disruptions happening due to improper sleep habits occur in areas of the brain involved in the regulation of sleep and wakefulness as well as cognitive function. n the new study, researchers in China examined 23 patients with primary insomnia and 30 healthy volunteers. All of the participants completed standardized questionnaires concerning their mental health and sleeping patterns. Each participant also underwent brain MRI with a specialized technique called diffusion tensor imaging, a sensitive tool that can probe deeper than the basic brain structure revealed by MRI to see how well neurons are connecting.

The MRI-based diffusion tensor imaging technique can be affected by numerous factors, such as the age of the patient and the type of MRI machine, scientist told Live Science. “We don’t fully understand normal variation in the scanning,” he said, adding that the technique is still only used as a research tool, not for diagnostics in the clinic.

Although scientists are still trying to learn exactly why people need sleep, animal studies show that sleep is necessary for survival. For example, while rats normally live for two to three years, those deprived of REM sleep survive only about 5 weeks on average, and rats deprived of all sleep stages live only about 3 weeks. Sleep-deprived rats also develop abnormally low body temperatures and sores on their tail and paws.
