Sleep issues commonly associated with depression include insomnia, hypersomnia, and obstructive sleep apnea. It is believed that about 20% of people with depression have obstructive sleep apnea and about 15% have hypersomnia.
Obstructive sleep apnea.
Excess body weight can lead to sleep apnea, but there are other causes too. A doctor can test to see if you have it and help you manage and treat it. By far, insomnia is the most common sleep problem linked to depression. Around 3 out of 4 adults who have depression also have insomnia.
Depression and sleep problems are closely linked. People with insomnia , for example, may have a tenfold higher risk of developing depression than people who get a good night's sleep. And among people with depression, 75 percent have trouble falling asleep or staying asleep.
However, primary insomnia also appears to raise the risk of depression, according to a 2016 meta-analysis . Depression-related insomnia can also be acute or chronic. Acute insomnia causes symptoms for less than 3 months , while chronic insomnia symptoms are present more than 3 nights per week for longer than 3 months.
It indicates that insomnia coexists with MDD. Insomnia is the main symptom of several common sleep disorders, but it often coexists with mental illnesses. In addition, insomnia can affect the trajectory of MDD and increase the severity and duration of this disorder [14].
But sleep and psychiatric disorders such as schizophrenia and depression are closely related. Psychiatric disorders are the leading cause of insomnia, the inability to sleep. In addition to insomnia, people with psychiatric disorders have other sleep problems, including sleepiness during the day, and nightmares.
Characteristic sleep-EEG changes in patients with depression include disinhibition of rapid eye movement (REM) sleep, changes of sleep continuity, and impaired non-REM sleep.
Lack of sleep can lead to symptoms, like lack of energy or motivation, that mimic those of depression. Other conditions that interrupt your sleep, including sleep apnea and sleep movement disorders, can also contribute to depression.
One of the most consistent symptoms associated with major depressive disorder is sleep disturbance. These problems with sleep regulation are not secondary to the illness; rather, they often precede the depressive episodes and can persist during remission.
Sleep disturbance is a core symptom of bipolar disorder. The diagnostic criteria indicate that during manic episodes there may be a reduced need for sleep and during episodes of depression, insomnia or hypersomnia can be experienced nearly every day (American Psychiatric Association, 2000).
Answer From Eric J. Olson, M.D. Waking up in the middle of the night is called insomnia, and it's a common problem. Mid-sleep awakenings often occur during periods of stress. Over-the-counter sleep aids rarely offer significant or sustained help for this problem.
Some people with depression may try to hide the signs from others, and others might not even realize that they have depression. Although well-known symptoms such as sadness or hopelessness can be easy to recognize, other signs of depression may be less obvious.
Terminal or postdormitional (or late) insomnia – where the sleeper awakens up too early and is not able to fall asleep again. Encyclopedia of Sleep.
Anxiety can cause racing or repetitive thoughts, and worries that keep you awake. You may also have panic attacks while you're trying to sleep. Depression and seasonal affective disorder (SAD) can make you sleep more, including staying in bed for longer or sleeping more often. Depression can also cause insomnia.
People in pain or discomfort often have difficulty getting deep sleep. Loud noises and bright lights in or near the sleeping environment may also make it difficult to get deep sleep. To get the best possible sleep, sleepers should keep their bedroom dark, quiet, and cool with a comfortable bed and pillows.
It is diagnosed when an individual has a persistently low or depressed mood, anhedonia or decreased interest in pleasurable activities, feelings of guilt or worthlessness, lack of energy, poor concentration, appetite changes, psychomotor retardation or agitation, sleep disturbances, or suicidal thoughts.
Doctors widely prescribe some antidepressants for people with anxiety. Examples include amitriptyline (Elavil), mirtazapine (Remeron), and trazodone (Desyrel). Melatonin-like medications: These medications mimic melatonin, a natural hormone that regulates the body's sleep-wake cycle and promotes sleep.
Behavior Changes and Mood Disorders
Determining the circadian secretion rhythm of melatonin can assist the clinician in diagnosing the type of mood disorder. In general, studies have reported decreased nocturnal melatonin levels in patients suffering from depression.
The more variation in wake up and sleep time, the worse mood and more chance of depression symptoms. An irregular sleep schedule can increase a person's risk of depression over the long term as much as getting fewer hours of sleep overall, or staying up late most nights, a new study suggests.
Living with depression can affect your sleep, causing more vivid dreams or nightmares. Sleep problems, in turn, can affect your mood, making it difficult to function during the day and impacting your quality of life.
When you suffer from depression, your brain is physically changed. Research by the National Institutes of Health shows that you lose gray matter volume (GMV) when you suffer from depression. This loss is caused by parts of your brain shrinking due to the hormone cortisol impeding the growth of your brain cells.
Disorders in cortisol secretion (particularly hypercortisolemia) may cause mental disorders and can be one of the many hormonal disorders accompanying these conditions, for example depression. About 50% percent of patients with newly diagnosed depression have been observed to have excessive cortisol secretion [7].
Cause and Effect
Approximately 50% of insomnia cases are related to depression, anxiety or psychological stress. Often the qualities of a person's insomnia and their other symptoms can be helpful in determining the role of mental illness in a person's inability to sleep.
Insomnia - being unable to fall asleep and stay asleep. This is the most common sleep disorder.
