Eating Disorders and Neurocognitive Disorders

Eating Disorders

  • Anorexia Nervosa

    • Definition: A condition where individuals starve themselves to avoid weight gain.

    • Common Reasons for Anorexia:

    • Genetic Influence: Hereditary factors influence the occurrence of eating disorders, particularly in women whose daughters may also develop anorexia due to learned behaviors.

    • Mental Disorders: Associated with conditions such as depression, drug addiction, and alcoholism.

    • Symptoms of Anorexia:

    • Physical Symptoms:

      • Dizziness

      • Fainting

      • Rapid weight loss

    • Psychological Symptoms:

      • Intense fear of weight gain (95% of cases)

      • Behavioral changes, often resembling a phobia of gaining weight.

    • Eating Habits:

      • Extremely small portions, like a single carrot or piece of lettuce.

      • Unlike bulimia, it does not typically involve bingeing and purging.

    • Physical Consequences:

      • Amenorrhea (no menstruation) due to low body fat.

      • Cognitive impairments affecting thinking.

      • Mood changes, including depression.

      • Altered brain chemistry.

      • Brittle hair and hair loss due to nutritional deficiencies.

      • Cardiovascular issues impacting heart function.

      • Hormonal disruptions leading to problems such as bone loss and complications with pregnancy (e.g., higher risk of miscarriage, low birth weight.

      • Increased sensitivity to cold and yellowing of skin.

      • Brittle nails.

  • Bulimia Nervosa

    • Definition: A condition that involves episodes of eating large amounts of food followed by purging to prevent weight gain.

    • Eating Patterns:

    • Bingeing on highly caloric soft foods, followed by guilt and anxiety.

    • Often involves purging behaviors within 20 to 30 minutes after eating.

    • Body Weight:

    • Individuals may appear normal weight or slightly overweight due to cycles of purging.

    • They may frequently wear loose-fitting clothes to hide body shape.

    • Purging Methods:

    • Use of laxatives, diet pills, diuretics, and excessive exercise to control weight.

    • Behavioral Aspects:

    • Patients sometimes weigh themselves backwards to avoid anxiety from seeing the number on the scale.

    • Common signs include abrasions on knuckles from inducing vomiting, oral health deterioration due to stomach acid, and emotional instability related to feeding and purging.

  • Risk Factors for Eating Disorders:

    • Occupational Pressures:

    • Pressure in professions like modeling, acting, or athletics where a lean physique is idealized.

    • Genetic and Biological Factors:

    • Heredity plays a role; mothers with eating disorders often have daughters who develop similar issues.

    • Biological disturbances, including hypothalamic issues and neurotransmitter imbalances (e.g., serotonin pathways).

    • Parental and Interpersonal Relationships:

    • Pressure from parents to succeed can influence the development of eating disorders.

    • Dysfunctional family dynamics leading to dependency or emotional distress.

    • Environmental Influences:

    • Impact of social media and societal standards of beauty, especially on adolescents.

  • Nursing Interventions:

    • Creating a trusting relationship with patients.

    • Utilizing a positive approach to promote self-esteem and self-image.

    • Outpatient programs and specialized homes for those with eating disorders, such as residence centers.

    • Monitoring and recording weights in non-anxiety-inducing ways (e.g., weighing backwards).

  • Comparative Analysis of Anorexia and Bulimia:

    • Anorexia involves starvation and extreme weight loss, while bulimia consists of binge-purge cycles.

    • Emotional states in both disorders include guilt, shame, and anxiety about body weight and appearance.

Neurocognitive Disorders

  • Definition: A group of conditions that disrupt cognitive function, including thinking, memory processing, and problem-solving abilities.

  • Conditions Included: Delirium, dementia (including Alzheimer's), and other neurodegenerative disorders like Parkinson's and Huntington's.

  • Delirium:

    • Definition: An acute disturbance characterized by confusion, disorientation, and fluctuations in consciousness.

    • Symptoms may include hallucinations and illusions.

    • Risk Factors: Substance intoxication, medication effects (especially in polypharmacy cases), and metabolic or neurological issues.

    • Delirium typically resolves upon addressing the underlying medical condition.

  • Dementia:

    • Definition: A chronic decline in mental processes due to brain disease, distinguished into mild and major types based on severity of symptoms.

    • Symptoms:

    • Memory disorders and personality changes.

    • Gradual decline in cognitive functions over months or years with difficulties in daily activities.

    • Behavioral disturbances that may include agitation or psychosis.

    • Stages:

    • Mild: Minor difficulties in daily living, forgetfulness in tasks or events.

    • Moderate: Increased support needed for basic living activities, potential wandering behavior.

    • Severe: Complete dependency on caretakers, comprehending surroundings becomes difficult, risk of incontinence, progressive motor dysfunction, potential loss of speech.

  • Alzheimer's Disease:

    • The most common cause of dementia, characterized by irreversible brain changes.

    • Predicted demographic of 7.2 million Americans aged 65 or older affected by 2025, predominantly women.

    • Symptoms: Memory loss, difficulty in language and abstract reasoning, progressive decline in physical and cognitive abilities.

    • Brain changes include abnormal protein deposits (amyloid beta and tau) leading to neuron damage and brain shrinkage.

    • Currently, no cure, but medications such as cholinesterase inhibitors can slow progression.

  • Other Neurocognitive Disorders:

    • Discussed briefly were Huntington's disease and Parkinson's disease, including symptoms and genetic implications. Specific focus was not given as the audience had covered these previously.

Somatic Disorders

  • Definition: Conditions where patients experience physical symptoms without identifiable medical causes.

  • Types:

    • Somatic Symptom Disorder: Real to the patient, symptoms cannot be explained medically, often related to significant stressors in life.

    • Factitious Disorder: Patients intentionally produce or feign illnesses for attention.

    • Examples include self-harm or manipulating medical conditions (e.g., injecting insulin).

    • Factitious Disorder Imposed on Another (by Proxy): A caregiver intentionally harms another (e.g., a child) to seek attention.

  • Malingering: Intentional production of false symptoms for external gain, such as avoiding work or legal responsibilities.

  • Prevention and Treatment: Patients experiencing these disorders should be believed and treated with respect; thorough medical assessments are crucial to distinguish between genuine medical issues and psychological conditions.
