“Amnestic sleep-related eating disorder”: No memory of sleep eating

She reported that she would wake up and find candy wrappers all around the bed, and crumbs in the bed, but so had no memory of eating them.

Researchers refer to this as “amnestic sleep-related eating disorder”.

Half awake and half asleep

In the CBS report, Dr. Mark Mahowald, medical director of the Minnesota Regional Sleep Disorders Center in Minneapolis, Minn., says that, “The brain can be literally half awake and half asleep.”

Sleep eating seen in people with sleep disorders

Timothy Morgenthaler from the Mayo Clinc reported on five case reports of amnestic sleep eating.

All patients had sleep disorders including restless leg syndrome, obstructive sleep apnea and sleep walking

In all five cases, people had sleep disorders as well as insomnia.

All patients had restless leg syndrome

All five patients had restless leg syndrome.

Three had sleep apnea, two had sleep walking

Three of the five patients also had obstructive sleep apnea, and two of the five patients had sleep walking.

None had daytime eating disorders

None of the five patients had a history of daytime eating disorders.

Two had history of eating in the middle of the night

Two of the five patients had a history of eating in the middle of the night prior to starting on Ambien (zolpidem).

Patient #1: 54-year-old woman

The first patient was a 54-year-old woman.

She had the uncontrollabe desire to eat within 30 minutes of falling asleep.

“She denied bedtime hunger, ate well during the day, and had a stable and normal weight,” the paper notes.

“She was frustrated and embarrassed by her inability to stop this nighly behavior,” they continued.

“She also complained that she often had difficulty remembering what she had read after taking [Ambien] zolpidem.”

She was taking numerous other medication, but the sleep eating stopped after she stopped taking the Ambien.

Patient #2: 67-year-old man

The second patient was a 67-year-old man who had insomnia related to restless leg syndrome which developed two years after the onset of Parkinson’s Disease.

The most dramatic episode of sleep eating involved him falling down 12 steps after eating, but he did not remember any of it the next day.

Patient #3: Nightly eating since age 15

The patient was a male who had nightly eating since he was 15-years-old.

Prior to starting on Ambien, he remembered eating at night.

After starting on Ambien, he experienced more eating episodes per night—two or three per night—increased calorie intake and weight gain, and did not remember most of the sleep eating episodes.

Patient #4: Nightly eating for 34 years

The fourth patient had nightly eating for 34 years prior to starting on Ambien, and had complete recall of each of these episode.

After starting on Ambien, her nightly eating episodes increased to three per night, and she did not remember two-thirds of them.
