Our Approach to PMDD
Premenstrual Dysphoric Disorder is a severe, cyclical condition that affects mood, cognition, and physical function in the luteal phase of the menstrual cycle.
Care focuses on understanding individual symptom patterns, stabilizing hormonal response, and improving functioning through personalized, longitudinal treatment integrating hormonal, neurological, and lifestyle factors.
Understanding PMDD
PMDD is distinguished from severe PMS, characterized by heightened sensitivity to normal hormonal fluctuations, particularly in the second half of the menstrual cycle.
Research indicates individuals with PMDD have:
- altered central nervous system responses to progesterone metabolites
- increased sensitivity in serotonin and GABA pathways
- cyclical symptom patterns that resolve after menstruation begins
Hormone levels may be normal — the response to them is not.
Common Signs of PMDD
Symptoms occur cyclically, emerging in the luteal phase and improving with menstruation onset.
Emotional & Cognitive Symptoms
- irritability or anger
- anxiety or panic
- depressed mood
- emotional sensitivity or frequent crying
- feeling overwhelmed or out of control
- difficulty concentrating
- memory changes or brain fog
Nervous System & Behavioural Changes
- insomnia or disrupted sleep
- severe fatigue or energy crashes
- agitation or restlessness
- social withdrawal
Physical Symptoms
- bloating
- breast tenderness
- headaches
- joint or muscle pain
- gastrointestinal changes
- fluid retention
Additional Patterns
- food cravings
- decreased libido
- worsening of existing conditions
Safety consideration. PMDD is associated with an increased risk of suicidal thoughts during the luteal phase. Care is available, and effective treatment can significantly reduce symptoms. If you are in crisis or thinking about harming yourself, call or text 9-8-8 (Suicide Crisis Helpline), available 24/7 across Canada, or call 9-1-1.
What Is Happening Physiologically
PMDD is driven by a neurohormonal interaction, not simply a hormone deficiency.
Key mechanisms include:
- sensitivity to progesterone metabolites like allopregnanolone
- altered GABA receptor response affecting mood and anxiety
- changes in serotonin signalling
- cyclical central nervous system shifts tied to ovulation
How We Assess PMDD
Diagnosis is based on pattern recognition, including:
- detailed symptom tracking across cycles
- menstrual and ovulatory history
- mood and functional impact evaluation
- screening for overlapping conditions
Lab testing may support broader hormonal and metabolic assessment.
How We Treat PMDD
Treatment is individualized and may combine multiple approaches:
Hormonal Strategies
- ovulation suppression
- progesterone modulation strategies
- targeted hormone therapy
Neurotransmitter Support
- medications supporting serotonin pathways
- integration with hormonal care
Lifestyle & Nervous System Support
- sleep stabilization
- stress regulation
- targeted nutritional strategies
Mental Health Support
- structured mood symptom support
- counselling integration
A Continuity Care Model
PMDD requires ongoing adjustment and pattern recognition.
Care includes:
- symptom response tracking over time
- medication access and adjustments
- coordination of hormonal and mental health strategies
Expected Outcomes
With appropriate care, individuals may experience:
- reduced mood symptom severity
- improved emotional stability
- better sleep and energy
- reduced anxiety and irritability
- improved daily functioning
- decreased cyclical disruption to work, relationships, and quality of life
