Some of you may have noticed that NeuroClean talks openly about neurodivergence, chronic overwhelm, burnout, sensory struggles and the way our homes often reflect our physical and mental health.
Over time, I’ve also started noticing something else.
A lot of my neurodivergent clients seem to share traits, symptoms or diagnoses linked to three conditions that are often misunderstood, misdiagnosed, overlooked or dismissed:
- PMDD (Premenstrual Dysphoric Disorder)
- PoTS (Postural Orthostatic Tachycardia Syndrome)
- Hypermobility Spectrum Disorder / hEDS
Research is increasingly showing overlap and co-morbidity between autism, ADHD and these conditions.
This post is NOT medical advice and I am NOT a doctor.
I am first aid trained, personally live with PMDD and hypermobility myself, have experience around PoTS, and my long-term special interests are psychology, sociology, disability and health conditions - especially where they intersect with neurodivergence and quality of life.
I’m sharing this because sometimes information changes lives.
Especially for people who have spent years being told:
- “everyone feels like that”
- “you’re just anxious”
- “you’re lazy”
- “you’re dramatic”
- “you need to exercise more”
- “you’re overreacting”
- or “your tests are normal”
💚 PMDD - More Than “Bad PMS” 💚
PMDD is a severe hormone-related disorder linked to the menstrual cycle with symptoms usually beginning 2 weeks before Period however for those with irregular cycles or other conditions affecting their hormones (such as pcos) this isn't always the case.
It can cause:
- extreme mood swings
- intense irritability or rage
- suicidal thoughts
- sensory overwhelm
- depression
- panic
- exhaustion
- brain fog
- feeling like “yourself disappears” before your period
Many autistic and ADHD people report their sensory issues, emotional regulation difficulties and executive dysfunction becoming significantly worse during hormonal changes. Research suggests people with ADHD are at much higher risk of PMDD.
PMDD is often missed because:
- it can look like depression, bipolar disorder, BPD or burnout
- many people don’t realise symptoms are cyclical
- women and AFAB neurodivergent people are historically underdiagnosed and misunderstood
- masking can hide the severity until someone burns out completely
💚 PoTS - “Why Do I Feel Like I’m Dying When I Stand Up?” 💚
PoTS affects the autonomic nervous system - the system responsible for things like heart rate, blood pressure and temperature regulation.
Common symptoms include:
- dizziness when standing
- rapid heart rate
- fainting or near fainting
- exhaustion
- heat intolerance
- nausea
- shakiness
- headaches
- brain fog
- adrenaline surges
- feeling weak after standing or showering
Many people with PoTS are repeatedly told it’s “just anxiety”.
PoTS is also commonly associated with hypermobility conditions and is seen frequently alongside neurodivergence.
💚 Hypermobility Spectrum Disorder / hEDS 💚
Hypermobility is NOT just “being flexible”.
For some people it can involve:
- chronic pain
- frequent sprains or injuries
- joints partially slipping out
- fatigue
- poor coordination
- digestive issues
- bruising easily
- chronic muscle tension
- poor body awareness
- pelvic pain
- headaches
- exhaustion from simply holding the body together
Many hypermobile people grew up being praised for being “bendy” without anyone recognising the pain, instability and fatigue underneath it.
Research and clinicians are increasingly recognising links between hypermobility, autism, ADHD and autonomic conditions like PoTS.
💚 Why This Matters 💚
A diagnosis doesn’t magically cure these conditions but understanding your body can change EVERYTHING. Once you understand what’s happening, you can start to:
- reduce shame
- stop pushing yourself past your limits
- learn symptom management
- advocate for accommodations
- prevent worsening symptoms
- understand burnout cycles
- work WITH your body instead of against it
For many neurodivergent people, unknowingly living with chronic health conditions leads to severe burnout, worsening mental health and a huge reduction in quality of life over time.
You do not need to “earn” support by collapsing first.
💚 If This Sounds Familiar 💚
Please speak to a GP or healthcare professional.
Keep symptom notes.
Track patterns.
Especially around:
- menstrual cycles
- standing
- fatigue
- pain
- dizziness
- sensory overload
- burnout
And remember:
Doctors are human.
Some are amazing.
Some are under-informed.
Some conditions are still poorly recognised.
If you genuinely feel something is being missed, it is okay to ask for a second opinion.
You know your body better than anyone else.
And whether you end up with a formal diagnosis or not, learning how to accommodate and support your body is still important.
Your symptoms are real.
Your struggles matter.
And you deserve support before you completely burn out trying to “push through”.
