Understanding Your Condition

What is Chronic Migraine?

Anorexia Nervosa (AN) is a serious, potentially life-threatening eating disorder characterized by a persistent restriction of energy intake, an intense fear of gaining weight or becoming fat, and a disturbance in self-perceived body shape or weight. Individuals with AN maintain a body weight significantly below what is considered normal or healthy for their age, height, and gender, typically through caloric restriction, excessive exercise, binge-eating/purging behaviors (in the binge-purge subtype), or combinations thereof. The disorder is associated with severe medical complications affecting nearly every organ system, including cardiovascular dysfunction, bone loss, hormonal imbalances, and neurological changes, with the highest mortality rate of any psychiatric disorder.

Healthy Function

What your body should do

A healthy relationship with food involves eating in response to physiological hunger and satiety cues, maintaining a body weight that is natural for the individual's genetic blueprint and metabolic needs. The hypothalamus appropriately regulates appetite through ghrelin (hunger hormone) and leptin (satiety hormone), while the enteric nervous system communicates hunger and fullness signals to the brain via the vagal nerve. The prefrontal cortex successfully regulates food-related impulses without excessive preoccupation. The menstrual cycle functions regularly in reproductive-age females, indicating adequate energy availability. Body temperature remains stable through appropriate thermoregulation. Energy levels support normal daily activities, exercise, and cognitive function. Bone mineral density is maintained through adequate nutrition and appropriate hormonal signaling. Cardiovascular function remains stable with normal heart rate variability and blood pressure regulation.

When Things Go Wrong

Signs of chronification

  • Pain threshold lowers over time
  • More frequent attacks
  • Brain stays in alert mode
  • Medication stops working

Commonly Associated

Conditions That Occur Together

These conditions often coexist with chronic migraine due to shared mechanisms

Related Condition

Major Depressive Disorder

50-70% comorbidity; shared neurobiological pathways involving serotonin and HPA axis; starvation itself causes depressive symptoms; social withdrawal and negative self-evaluation are common features

Related Condition

Anxiety Disorders

40-60% comorbidity; generalized anxiety, social anxiety, and OCD commonly co-occur; anxiety about food, eating, and weight; often pre-dates AN development

Related Condition

Obsessive-Compulsive Disorder

10-20% comorbidity; overlapping features of rigidity, rituals, and preoccupations; food-related compulsions common; may be distinct subtype

Related Condition

Autism Spectrum Disorder

10-15% comorbidity; shared features of rigidity, sensory issues around food, and restricted interests; ASD may predispose to AN development

Related Condition

Substance Use Disorders

15-25% comorbidity; alcohol and stimulant use to suppress appetite or control weight; may develop in recovery from AN

Related Condition

Post-Traumatic Stress Disorder (PTSD)

15-25% comorbidity; trauma often precedes AN; restrictive eating may represent attempt to regain control; ACE scores correlate with AN severity

Related Condition

Personality Disorders

20-30% comorbidity, particularly avoidant, dependent, and OCPD; perfectionism and rigidity in OCPD may predispose; avoidant personality involves social withdrawal

Related Condition

Root Causes

What's Driving Your Migraines

Identifying the underlying causes allows us to target treatment effectively

1

Genetic Predisposition

40-70% heritability; family history increases risk 4-10x; genes involved in serotonin transport (5-HTTLPR), dopamine signaling (DRD2, DRD3), and BDNF; epigenetic modifications from environmental triggers

Family history; genetic testing for risk variants; epigenetics assessment

2

Neurobiological Dysregulation - Reward and Motivation

45% - Altered dopamine and opioid reward pathways; food becomes aversive rather than rewarding; increased reward sensitivity to weight loss

Clinical assessment; fMRI studies; psychometric testing

3

Serotonin Dysregulation

40% - Altered serotonergic activity affects mood, impulse control, and satiety signaling; perfectionism and anxiety linked to 5-HT dysfunction

Serotonin metabolites; clinical response to SSRIs; tryptophan ratio

4

Temperamental Factors

35% - Perfectionism, anxiety, harm avoidance, and negative emotionality are risk traits; obsessionality and rigidity

Temperament assessment (TCI, ASQ); personality evaluation

5

Body Image Dysregulation

50% - Distorted body perception; inability to accurately judge own body size; overestimation of body size

Body image assessment tools; figural stimuli; ecological momentary assessment

6

Perfectionism

45% - Perfectionistic traits drive extreme dietary control; black-and-white thinking; fear of making mistakes

Perfectionism scales (APS-R, CDP); clinical interview

7

Early Life Trauma and Adverse Childhood Experiences

30-50% - ACEs correlate with AN development; trauma may precede onset; controlling eating as coping mechanism

ACE questionnaire; trauma history; dissociation assessment

8

Social and Cultural Factors

30% - Cultural emphasis on thinness; participation in weight-focused sports or activities; teasing or bullying about weight

Social history; cultural assessment; history of weight-related teasing

9

Family Dynamics

25% - Enmeshment, overprotection, rigidity, and conflict avoidance in family systems; high expressed emotion

Family assessment; family meals observation; FACES-IV

10

Stressful Life Events

30% - Onset often follows significant stressors; illness, loss, transition; loss of control in one domain leads to control in eating

Life events assessment; stress vulnerability evaluation

11

Autonomic Dysregulation

25% - Vagal hypertonicity contributes to bradycardia, hypotension, and gastrointestinal dysmotility; autonomic inflexibility

Heart rate variability; tilt table testing; autonomic function tests

12

Inflammation and Immune Activation

20% - Low-grade inflammation may affect brain function; increased pro-inflammatory cytokines; may affect appetite regulation

CRP, IL-6, TNF-alpha; autoimmune panel
