Depression and Sleep: An Expert Interview with Prof. Dr. Richter

Prof. (Nuremberg University of Applied Sciences) Dr. med. Kneginja Richter, MHBA, is an experienced specialist in psychiatry, psychotherapy, and sleep medicine and heads the CuraMed Day Clinic in Nuremberg. With her many years of experience and specialization in psychiatry, psychotherapy, sleep medicine, and neurostimulation, she places particular emphasis on providing holistic and innovative treatment for her patients. A central component of her work is the combination of proven psychotherapeutic methods with modern techniques such as repetitive transcranial magnetic stimulation (rTMS), which is particularly effective in treating depression and other mental health conditions.

With her additional Master of Health Business Administration (MHBA) degree, Prof. Dr. Kneginja Richter has expanded her medical expertise with business management skills, which particularly qualifies her for leadership positions in the healthcare sector. At the day clinic, Prof. Dr. Richter and her interdisciplinary team offer a wide range of treatments tailored to the specific needs of patients. In addition to depression and anxiety disorders, this includes the treatment of sleep disorders, tinnitus, panic disorders, obsessive-compulsive disorders, trauma-related disorders, chronic pain disorders, as well as integrative treatment for burnout, chronic fatigue, and chronic somatic illnesses with psychosomatic effects.

The day clinic offers the advantage of structured daytime treatment with an intensive psychotherapy program consisting of three 50-minute individual sessions per week, while patients can return to their familiar home environment in the evenings. This approach promotes the application of learned therapeutic strategies to everyday life and supports sustainable, practical recovery. Thanks to the modern facilities at the HighTech Center Nuremberg and the comprehensive diagnostic and therapeutic options available, Prof. Richter is able to provide excellent care and personalized, individually tailored treatment plans.

The interdisciplinary and integrative approach of the CuraMed Day Clinic combines psychodynamic and behavioral medicine approaches with body-oriented therapies and device-based procedures to holistically promote patients’ well-being and open up long-term prospects for their health. Prof. Richter and her team are dedicated to providing optimal support to their patients throughout their recovery process and helping them lead stronger and more fulfilling lives.

The CuraMed Day Clinic also treats many patients who suffer from sleep disorders in conjunction with depressive disorders. The editorial team of the Leading Medicine Guide was able to learn more about this in a conversation with Prof. Dr. Richter.

Depression and sleep disorders are closely related health issues that frequently occur together and can exacerbate one another. While depression is often accompanied by profound psychological distress and feelings of hopelessness, listlessness, and inner emptiness, sleep disorders impair rest and lead to exhaustion and concentration problems. This connection poses a major challenge, as poor sleep quality can exacerbate depressive symptoms, and conversely, depressive moods can impair sleep.

Depression and sleep disorders are involved in a complex interplay that can mutually reinforce both conditions and worsen the course of the illness. 

In depression, the sleep-wake cycle is often disrupted, manifesting in various forms of sleep disturbances: difficulty falling asleep and staying asleep, waking up too early in the morning, or generally non-restorative sleep are among the typical symptoms. In many cases, sleep architecture is altered, meaning that the phases of deep sleep or the REM phase—during which most dreams occur and which is important for emotional processing—are shortened or interrupted. Such disrupted sleep, in turn, can exacerbate depressive symptoms and impair recovery, as it weakens the body’s own mechanisms for regulating emotions. 

“Approximately 80% of people suffering from depression have difficulty falling asleep and staying asleep, and suffer from chronic insomnia. This is characterized by the fact that those affected take a long time to fall asleep, wake up frequently after falling asleep, and are very tired the next day. In contrast, about 20% of people with depression suffer from excessive sleep—women and younger people are more frequently affected by this,” Prof. Dr. Richter states at the beginning of our conversation and describes the treatment options available following a detailed and individualized medical history:

“We treat depression with high-frequency psychotherapy, which takes place three times a week in individual sessions and additionally in group sessions over a period of three to six weeks, and supplement this with antidepressants as needed. If treatment takes place during the fall and winter months, we also combine it with light therapy and support the process with neurostimulation, the so-called rTMS procedure. Repetitive Transcranial Magnetic Stimulation is a non-invasive neurological treatment method that uses magnetic pulses to stimulate specific areas of the brain. The goal is to improve patients’ motivation and mood. Patients who have developed a sleep disorder due to depression first undergo a comprehensive sleep assessment. This is conducted using a smartwatch-like device that patients wear on their wrist for one week—essentially a “sleep lab on the go.” The patient can sleep in their own bed and then return the device for evaluation, so that the results can be communicated immediately.” In addition, mobile diagnostics are conducted at home in the patient’s familiar sleeping environment to diagnose sleep apnea, restless legs syndrome, and other sleep disorders. The evaluation and discussion of the findings usually take place as early as the following day.

Serotonin plays a central role in regulating mood and sleep, and serotonin levels are often reduced in many patients with depression. These imbalances can contribute to both depressive symptoms and sleep disorders, as serotonin has a direct influence on sleep architecture, particularly the REM phase. Norepinephrine is also important for mood regulation, and dysregulation of this neurotransmitter can lead to a lack of motivation, which negatively affects sleep. Dopamine, the neurotransmitter associated with reward mechanisms, can also influence sleep regulation, and reduced dopamine activity is frequently observed in depression. In addition, cortisol, the stress hormone, plays a crucial role. Chronically elevated cortisol levels are common in patients with depression, and these stress responses can significantly impair sleep quality, which can result in a vicious cycle of insomnia and exacerbated depressive symptoms. Sleep architecture itself is altered in many patients with depression, which can manifest as an earlier onset and more intense REM sleep, as well as shorter periods of deep sleep. These changes impair the ability to regulate emotions and negatively affect quality of life. 

“There are also patients who suffer from chronic sleep disorders. We can treat these at the CuraMed Day Clinic in Nuremberg without medication: The patient comes to us 4–6 times over a two-week period as part of a day clinic sleep program for counseling and can keep a sleep diary. Based on the recorded data—when the patient went to bed, what they did during the day, and how long they slept—we have all the necessary information to create a personalized sleep plan and to provide cognitive therapy for insomnia. This therapy, which is also enshrined in the guidelines, helps approximately 70% of patients. In addition, we offer patients a sleep school. If the therapy does not provide sufficient relief, a low-dose medication with no risk of dependence can also be prescribed,” explains Prof. Dr. Richter regarding the success of this treatment option.

Sleep disorders are common precursors to depression and can serve as early warning signs, as they are often among the first symptoms to appear in those affected. 

The reciprocal relationship between sleep disorders and depression is based on various neurobiological mechanisms that regulate both mood and sleep. A key mechanism that explains the link between sleep and depression is the dysregulation of neurotransmitters such as serotonin, norepinephrine, and dopamine. These neurotransmitters are crucial for regulating mood and the sleep-wake cycle. In people with depression, an imbalance of these neurotransmitters is frequently observed, which negatively affects both sleep architecture and mood. Serotonin levels, in particular, play an important role, as they regulate not only mood but also sleep. A serotonin deficiency can lead to difficulty falling asleep and reduced sleep quality, which in turn can increase the risk of a depressive episode. These interactions are exacerbated by changes in the circadian rhythm—the biological 24-hour cycle regulated by light and darkness. In patients with depression, this rhythm can become disrupted, leading to sleep problems and, consequently, an intensification of depressive symptoms. The early detection of sleep disorders as an indicator of the risk of a depressive episode is crucial for taking preventive measures in a timely manner. 

“Sleep disorders are often a precursor to mental health disorders and burnout. There are preventive steps one can take to address this. For patients who, for example, overthink before falling asleep, there are specific techniques. When falling asleep, you should focus on pleasant, soothing feelings and images in your mind—then you’ll usually fall asleep within 20 minutes. Improving sleep hygiene—which includes maintaining a regular sleep routine, creating an optimal sleep environment, and avoiding stimulants such as caffeine and nicotine before bedtime—is essential. Consistent sleep hygiene can help shorten the time it takes to fall asleep and improve sleep quality. You also shouldn’t stay in bed too long if you can’t sleep. A TV in the bedroom is also rather counterproductive and is often used by traumatized people as a sleep aid because it makes them feel they aren’t alone. In addition, the blue light from the TV suppresses the release of melatonin. Many people also watch TV while lying down, which mistakenly signals to the body that it’s time to sleep. “Those who enjoy watching TV should therefore do so while sitting up. Ideally, alcohol should be avoided entirely or consumed at least two hours before bedtime, as it otherwise makes the body restless,” advises Prof. Dr. Richter.

In addition, fostering stress-coping mechanisms plays a crucial role. Techniques such as mindfulness meditation, yoga, or progressive muscle relaxation can not only help improve sleep quality but also enhance overall emotional well-being. Regular physical activity is another key factor that not only promotes sleep but also reduces stress and lifts one’s mood. Moderate exercise, such as walking or swimming, can help improve sleep quality and reduce symptoms of depression. 

Hypersomnia is a sleep disorder characterized by excessive daytime sleepiness and a persistent need for sleep. 

“The causes can be varied, ranging from primary sleep disorders such as idiopathic hypersomnia—a sleep disorder with no identifiable cause—to secondary causes such as sleep apnea, depression, neurological disorders, or side effects of certain medications. Therefore, it is essential to rule out any organic causes of hypersomnia before consulting a psychologist. Using a smartwatch monitoring device, it must first be determined whether the patient actually sleeps for more than nine hours and is still tired. In this case, an MRI of the skull is recommended to rule out certain inflammations in the brain. Thyroid function should also be checked, as an underactive thyroid can lead to increased fatigue. Iron levels in the body must also be assessed, as iron deficiency can cause extreme fatigue. A complete blood count and an allergy test are also among the necessary examinations to rule out physical causes of hypersomnia. If these tests reveal no abnormalities, the only remaining cause is usually a psychogenic component,” explains Prof. Dr. Richter, adding:

“At this stage, the patient should be evaluated for depression, which can then be treated accordingly. However, there is also the condition known as fatigue, which is very common. In this case, the patient is in a state of persistent tiredness. Fatigue can result from cancer, neurological disorders, or as a consequence of long COVID. If the cause is psychogenic, treatment involves psychotherapy and measures to promote wakefulness, such as daily light therapy, increased physical activity, and relaxation exercises. People with hypersomnia often have impaired function of the sympathetic nervous system and experience high levels of internal stress. Therefore, therapeutic measures such as yoga or meditation help restore inner balance. It is important to work with the patient to figure out “where all the energy is going.”

The impact of hypersomnia on the quality of life of those affected can be significant. People who suffer from hypersomnia often report difficulties in their daily routines, such as at work, at school, or in their social lives. They frequently have problems with concentration and memory, which leads to reduced performance. This constant fatigue can also contribute to emotional problems such as anxiety or depression, which further exacerbate the symptoms.

“In today’s world, sensory overload also plays a major role when it comes to states of exhaustion. Media consumption—especially through social media and screen-based work—is very high and overstimulates our brains, causing us to lose energy. We mustn’t forget how taxing it is for the brain to process 20 different pieces of information simultaneously on a screen. This is different from flipping through or reading a newspaper. People who own dogs, for example, have a natural safeguard against depression because they spend time outdoors in daylight every day, which triggers the release of happiness hormones. In addition, nature stimulates the nerve cells in the brain,” explains Prof. Dr. Richter.

Targeted pharmacological treatment may be appropriate if sleep disturbances persist over a longer period and depression therapy alone is insufficient. 

In such cases, antidepressants that also promote sleep are often used, such as certain tricyclic antidepressants or the latest medications that do not cause dependence. “Taking medication should always be discussed with a doctor. The general fear of medication is exaggerated. If sleeping pills, for example, help people process trauma, then that’s fine for a certain period of time, as long as they help the person. That’s what medication is for—to help people. Conversely, many of the patients’ symptoms here at the clinic improve even without medication. However, if necessary, we also prescribe psychotropic drugs when needed. We handle this very cautiously, and the decision is always made on a case-by-case basis. Furthermore, most psychotropic medications are not addictive. In cases of moderate depression, however, psychotherapy should be the primary treatment. “Psychotherapy is very effective, especially in combination with neurostimulation,” explains Prof. Dr. Richter. With these words, we conclude our conversation.

Thank you very much, Professor Dr. Richter, for the insight into your work at the CuraMed Day Clinic in Nuremberg.
