Circadian Rhythm

Circadian rhythm sleep disorders (CRSD) can cause problems with a person’s ability to fall asleep or stay asleep. Normally, the body’s sleep-wake cycle is perfectly in sync with the cues it receives from the environment, but when the cycle is disrupt, it’s know as a circadian rhythm disorder. People who have CRSD have trouble falling asleep or staying asleep, and their sleep may be of poor quality. Affected individuals can have trouble completing daily tasks.

Irregular sleep-wake rhythm is a condition in which the sleep-wake cycle is disrupt

An irregular sleep-wake rhythm disorder (ISWRD) affects the body’s circadian rhythm. These rhythms are necessary for normal life, from completing daily tasks to maintaining a relationship. An accurate diagnosis is crucial, as improper treatment may worsen the condition. To identify ISWRD, your doctor will look at your current sleeping habits and patterns. For this purpose, your doctor may ask you to keep a sleep diary. This helps him or her determine the type of irregular sleep-wake rhythm disorder you have.

People with ISWR are often unable to get adequate sleep. While they may get an equal amount of sleep, the deepest sleep they experience is usually not as deep as that required for the body’s regenerative processes. Many social and professional obligations may conflict with the onset of irregular sleep patterns, causing a person to feel isolated and depressed. They may also develop poor eating habits and lose their memory. Modalert is best medicine to maintain sleep-wake cycle.  

While ISWRD is rare, it is a common symptom of a malfunctioning body clock. Unlike shift work and jet lag, irregular sleep-wake rhythm disorders are often trigger by other neurological problems. Some patients with ISWRD, for example, may also have dementia. It is important to seek medical treatment as soon as symptoms start affecting their lives. The treatment for ISWRD depends on the underlying cause.

Melatonin receptor stimulant treatment

There are a number of benefits of melatonin receptor stimulation for patients with circadian rhythm sleep disorders. During discrete time windows, melatonin can phase-shift a person’s circadian clock. There are several commercially available melatonin receptor agonists. Tasimelteon is approve for use in the treatment of non-24 sleep-wake disorder.

A recent study showed that Tasimelteon, a melatonin receptor agonist developed by Vanda Pharmaceuticals Inc. Bristol-Myers Squibb Company, under licence significantly decreased sleep onset latency and reset the circadian melatonin rhythm. This research has potential for use in jet lag, shift work, and other circadian rhythm sleep disorders.

While it is not clear if the melatonin receptor agonist will work, the MT1 and MT2 receptors in the brain are involve in the regulation of circadian rhythm. Melatonin is associate with a high density of these receptors in the SCN and other organs, and their activity is regulated by the body’s internal clock. Other biological effects of melatonin remain to be understand, including its role in the regulation of the sleep-wake cycle and its potential as a neurogenic/neuroprotective agent.

In addition to regulating the circadian rhythm, Modalert 200 helps reverse the complications of SBD. Research on modafinil has found that it prevents glucose accumulation in sleep apnea animals, inhibits the production of inflammatory cytokines, and protects against cardiac hypertrophy in rats. The hormone also inhibits the expression of fibrotic markers.

Free-running type of CRSD

Free-running Type of Circadian rhythm sleep disorders occurs when the body’s internal clock is not entrain to a 24-hour schedule. This disorder can be common among blind people, as they cannot sense light and thus their sleep pattern shifts later each day. This disorder may also be cause by a neurological or genetic disorder, but it is rarely seen in sighted individuals. If you are prone to free-running Type of Circadian rhythm sleep disorders, here are some tips for you:

First, the disease itself is inherit; people with this disorder are more likely to experience a delayed onset of sleep. Likewise, those with Free-running Type of Circadian rhythm sleep disorders tend to have shorter free-running periods than their counterparts with other types. This may be because of a mutation in the PER2 gene, which causes the protein to not phosphorylate at the necessary amino acid.

The Free-running Type of Circadian rhythm sleep disorders can also be cause by an abnormality in the body’s light sensitivity. This disorder occurs when the body’s preferred sleep period shifts 1-2 hours later than normal. It can also occur due to exposure to bright light or age-related changes in the brain. It is common among nursing home patients and people with a disorganized lifestyle.
