Getting SAD is more than having the blues

University of Rochester doctor reviews seasonal affective disorder

While many people believe that Seasonal Affective Disorder (SAD) amounts to feeling gloomy in the winter, a University of Rochester research review emphasizes that SAD is actually a subtype of major depression and should be treated as such.

Lead author Stephen Lurie, M.D., Ph.D., an assistant professor of Family Medicine at the University of Rochester Medical Center, also noted that SAD is sometimes missed in the typical doctor's office setting.

"Like major depression, Seasonal Affective Disorder probably is under-diagnosed in primary care offices," Lurie said. "But with personalized and detailed attention to symptoms, most patients can be helped a great deal."

New, preliminary studies link SAD to alcoholism or Attention Deficit Hyperactivity Disorder (ADHD). However, not all people with SAD will have ADHD, according to the review article for the American Academy of Family Physicians.

"The important message here is that if you are a patient who has been diagnosed with a mental illness of any kind, don't just assume that any new mental or emotional problem is due to that illness," Lurie said. "Specifically, if you have ADHD and you feel worse in the winter, don't just assume it's your ADHD getting worse. It could actually be SAD – and you should see your doctor because ADHD and SAD are treated entirely differently."

Although SAD has only been studied in adults, parents of children with ADHD should be sensitive to seasonal patterns of behavior and report any changes to a doctor, Lurie said.

Emerging evidence also shows that a pattern of seasonal alcohol use or abuse is associated with SAD. Patients might be self-medicating to cope with an underlying depression, researchers said.

Treatment for SAD includes light therapy, medications such as antidepressants, and cognitive behavior therapy. Each option seems to be effective, Lurie said, but none has been proven superior.

For some patients, SAD is precipitated by darker days causing a shift in 24-hour hormonal rhythms. The loss of natural light outdoors can be replaced with treatment by indoor light-therapy units designed for SAD. Light therapy is best delivered in the morning, when it can regulate the daily pattern of melatonin secretion, the review said.

Treatment with cognitive therapy has been shown to improve a person's dysfunctional thoughts and attitudes and other symptoms in patients with major depression, but no large studies have established whether this type of treatment is effective for SAD.

Doctors often prescribe antidepressants such as Zoloft for SAD. But most of the clinical studies have compared the drug therapy to a placebo pill rather than to light therapy, making it difficult to determine if one treatment is better, the review said.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
