context_page_description: Many memory impairments exist as a result from or cause of eating disorders. Eating disorders are characterized by abnormal and disturbed eating patterns that affect the lives of the individuals who worry about their weight to the extreme. These abnormal eating patterns involve either inadequate or excessive food intake, affecting the individual's physical and mental health.
  In regard to mental health, individuals with eating disorders appear to have impairments in executive functioning, visual-spatial ability, divided and sustained attention, verbal functioning, learning, and memory. Some memory impairments found in individuals with ED, are due to nutritional deficiencies, as well as various cognitive and attentional biases. Neurobiological differences have been found in individuals with ED compared to healthy individuals, and these differences are reflected in specific memory impairments. There are certain treatments and effects of treatments, aimed at these ED-specific memory impairments. Animal research and areas of future research in relation to ED and memory, are also integral to understanding the effects of ED on memory.
context_section_description: The development of animal models for binge eating has been necessary, because the mechanisms underlying the physiological and neural effects are not very well understood. Since the emotional aspects such as distress and loss of control prove difficult to model in animals, the central feature of the binge eating disorder, was attempted to be mimicked. Sham-feeding was the most prominent model used to study BED.
