Pitt-led study shows that SAD sufferers, like insomniacs, misreport sleep patterns due to depression
PITTSBURGHLying awake in bed plagues everyone occasionally, but for those with seasonal affective disorder, sleeplessness is routine. University of Pittsburgh researchers report in the Journal of Affective Disorders that individuals with seasonal affective disorder (SAD)a winter depression that leads to loss of motivation and interest in daily activitieshave misconceptions about their sleep habits similar to those of insomniacs. These findings open the door for treating seasonal affective disorder similar to the way doctors treat insomnia.
Kathryn Roecklein, primary investigator and assistant professor in Pitt's Department of Psychology within the Kenneth P. Dietrich School of Arts and Sciences, along with a team of researchers from Pitt's School of Medicine and Reyerson University, investigated why, according to a previously published sleep study by the University of California, Berkeley, individuals with seasonal affective disorder incorrectly reported that they slept four more hours a night in the winter.
"We wondered if this misreporting was a result of depression symptoms like fatigue and low motivation, prompting people to spend more time in bed," said Roecklein. "And people with seasonal affective disorder have depression approximately five months a year, most years. This puts a significant strain on a person's work life and home life."
Roecklein and her team interviewed 147 adults between the ages of 18 and 65 living in the Pittsburgh metropolitan area during the winters of 2011 and 2012. Data was collected through self-reported questionnaires and structured clinical interviews in which participants were asked such questions as: "In the past month, have you been sleeping more than usual?" and "How many hours, on average, have you been sleeping in the past month? How does that compare to your normal sleep duration during the summer?"
In order to understand participants' ideas about sleep, Roecklein's team asked them to respond to questions such as "I need at least 8 hours of sleep to function the next day" and "Insomnia is dangerous for health" on a scale from 0 to 7, where 7 means "strongly agree" and 0 means "disagree completely."
Roecklein and her team found that SAD participants' misconceptions about sleep were similar to the "unhelpful beliefs" or personal misconceptions about sleep that insomniacs often hold. Due to depression, individuals with SAD, like those with insomnia, may spend more time resting in bed, but not actually sleepingleading to misconceptions about how much they sleep. These misconceptions, said Roecklein, play a significant role in sleep cognition for those with seasonal affective disorder.
"We predict that about 750,000 people in the Pittsburgh metro area suffer from seasonal affective disorder, making this an important issue for our community and the economic strength and vitality of our city," said Roecklein. "If we can properly treat this disorder, we can significantly lower the number of sufferers in our city."
Roecklein's research data suggests that addressing, understanding, and managing these "unhelpful beliefs" about sleep by way of psychotherapy could lead to improved treatments for seasonal affective disorder. One of the most effective treatment options for insomnia, said Roecklein, is cognitive behavioral therapy for insomnia (known as CBT-I), which aims to help people take control of their thinking to improve their sleep habits as well as mood, behavior, and emotions.
Roecklein's next research project aims to improve treatment for seasonal affective disorder by studying light perception and biological clock synchronization. Light from the environment synchronizes internal biological rhythms with the timing of dawn and dusk, which naturally changes with the seasons. This synchronization allows people to be awake and alert during the day and to sleep at night. Roecklein will examine whether people with seasonal affective disorder perceive this light from the environment differently because of changes in the function of neurological pathways from the eye to the brain. This could help uncover reasons why people suffer from seasonal affective disorder and could suggest new treatment options.

Pats player Hernandez taken from home in handcuffs
ATTLEBORO, Mass. (AP) ? New England Patriots tight end Aaron Hernandez was taken from his home in handcuffs Wednesday morning, more than a week after a Boston semi-pro football player was found dead in an industrial park a mile from Hernandez's house.
Less than two hours later, the Patriots announced they had released Hernandez.
Odin Lloyd, a 27-year-old semi-pro football player for the Boston Bandits, was found slain June 17. Officials ruled the death a homicide but did not say how Lloyd died.
Lloyd's relatives said he was dating the sister of Hernandez's fiancee, that the two men were friends and that the men were out together on the last night of Lloyd's life.
It's unclear why Hernandez was taken into custody Wednesday before 9 a.m. and put into the back of a police cruiser. He was wearing a white V-neck T-shirt, with his arms inside the shirt and behind his back as he was led from his North Attleborough home. He casually spit into some bushes on his way to the car.
Hernandez was arrested on a state police warrant at about 8:45 a.m. and was being booked at the North Attleborough police station, state police said on the agency's Twitter account. State police said they won't discuss the charge against Hernandez until it's presented in Attleboro District Court later Wednesday.
The Associated Press emailed a message to his attorney, Michael Fee, who hasn't discussed the investigation beyond acknowledging media reports about it. A message also was left with the Bristol County district attorney's office.
At about 10:20 a.m., the Patriots announced they had released Hernandez and expressed sympathy to Lloyd's family and friends.
"Words cannot express the disappointment we feel knowing that one of our players was arrested as a result of this investigation," the Patriots said in a statement. "We realize that law enforcement investigations into this matter are ongoing. We support their efforts and respect the process. At this time, we believe this transaction is simply the right thing to do."
Lloyd's mother, Ursula Ward, declined to comment at her Boston home Wednesday morning.
"Nothing to say, please. Thank you," she said, before shutting the door.
State police have searched in and around Hernandez's sprawling home in North Attleborough several times. At least three search warrants have been issued in connection with the investigation.
Reporters have been camped for days outside the home on the Rhode Island line, not far from the stadium where the Patriots play. They reported Tuesday that Hernandez got a visit from Boston defense attorney James Sultan.
The Patriots drafted Hernandez, who is originally from Bristol, Conn., out of the University of Florida in 2010. Last summer, the team gave him a five-year contract worth $40 million.
Patriots spokesman Stacey James has said the team did not anticipate commenting publicly during the police investigation.

Opening statements begin in Zimmerman trial
SANFORD, Fla. (AP) ? George Zimmerman's defense attorneys can use statements the neighborhood watch volunteer made to a police officer and neighbor immediately after he fatally shot 17-year-old Trayvon Martin.
Judge Debra Nelson made the ruling Monday that the remarks could be used shortly before opening statements in Zimmerman's second-degree murder trial.
Zimmerman told the officer and neighbor that he was yelling for help but nobody responded during his confrontation with Martin.
Zimmerman is pleading not guilty to second-degree murder, claiming self-defense.
Arguments over whether the remarks could be used by the defense delayed opening statements by a few minutes.
