Chronotherapeutics (light and wake therapy) in affective disorders
Psychological Medicine
|July 28, 2005
Summary
Wake therapy offers rapid antidepressant effects, improving 60% of patients within hours. Combining it with light therapy or medication can prevent relapse, providing effective depression treatment options.
Area of Science:
- Chronotherapeutics
- Affective Disorders
- Psychiatry
Background:
- Review of evidence on chronotherapeutic interventions for depression as of November 2004.
- Recommendations by the Committee on Chronotherapeutics, International Society for Affective Disorders (ISAD).
Discussion:
- Wake therapy (sleep deprivation) is a rapid antidepressant, effective across diagnostic subtypes.
- Light therapy is effective for major and seasonal depression, as an adjuvant or standalone treatment.
- Combination therapies (wake, light, SSRIs, lithium) show promise for rapid and sustained antidepressant response.
Key Insights:
- Wake therapy achieves rapid antidepressant response in approximately 60% of patients.
- Light therapy potentiates antidepressant response and benefits chronic depression patients.
- Preventative strategies include daily light therapy, SSRIs, lithium, or sleep phase advance.
Outlook:
- Urgent need for new strategies for residual depressive symptoms.
- High priority for clinical trials of wake and adjuvant light therapy.
- Long-term recurrence studies are crucial for chronotherapeutic interventions.

01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
01:15Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:24Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:24Sleep-Wake Cycles
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

01:23Antidepressant Drugs: MAOIs and Other Agents
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
