Psychiatric Conditions
Designed for a 60-second scan in primary care. Use this to explain why this theory fits, what would weaken it, and which tests are most worth discussing.
Why this still fits
My brain fog is happening in the context of psychiatric symptoms, but I want help separating the illness itself from medication effects, sleep disruption, substances, and medical mimics.
What would weaken it
- -No clear psychiatric syndrome, episode history, or medication burden that makes this lane clinically meaningful.
- -The fog is better explained by sleep apnea, endocrine disease, anemia, autonomic dysfunction, substance effects, or neurological illness.
- -The label stays broad and vague instead of resolving into a specific condition with a coherent treatment path.
Key points to communicate
- •Please narrow this to a real differential instead of leaving it as a vague psychiatric bucket.
- •Please separate illness effects from medication effects and from medical mimics.
- •If you think this is psychiatric, I want to know which screens, timelines, and safety questions matter most.
Bring this to the visit
- •A one-page timeline of when the fog changed versus when mood, panic, flashbacks, compulsions, psychotic symptoms, or medication changes happened.
- •Seven days of sleep timing, awakenings, and any nights with very little sleep but unusually high energy.
- •Current medications, recent dose changes, and the list of alcohol, cannabis, benzodiazepine, antihistamine, or stimulant use that might muddy cognition.
- •Any screening scores you already completed: PHQ-9, GAD-7, MDQ, or PCL-5.
- •Examples of what's actually failing: word-finding, processing speed, planning, attention, memory, self-care, or work performance.
- •Family history of bipolar disorder, psychosis, severe depression, OCD, or suicide if known.
Useful screening structure
- -PHQ-9 for depressive load
- -GAD-7 for anxiety load
- -MDQ when bipolar-spectrum illness is a real possibility
- -PCL-5 when trauma symptoms may be driving shutdown, hyperarousal, or dissociation
- -Medication review and anticholinergic-burden review if the regimen is cognitively costly
Tests and measurements to discuss
phq-9
What this helps clarify: Depression screening - overlap with brain fog symptoms
Range context
Score <5
How to use the result
Save the result with date and symptoms from the same week.
gad-7
What this helps clarify: Patient-facing anxiety screener route matching the short GAD-7 label used in results and referrals.
Range context
0-21 score bands
How to use the result
Save the result with date and symptoms from the same week.
mdq
What this helps clarify: Patient-facing Mood Disorder Questionnaire route used when bipolar-spectrum illness is part of the differential.
Range context
Positive / negative screen context
How to use the result
Save the result with date and symptoms from the same week.
pcl-5
What this helps clarify: Patient-facing PTSD Checklist route used when trauma symptoms may be driving the cognitive picture.
Range context
0-80 score bands
How to use the result
Save the result with date and symptoms from the same week.
cbc-cmp
What this helps clarify: Baseline panel combining complete blood count and metabolic chemistry for broad screening context.
Range context
Lab reference interval
How to use the result
Save the result with date and symptoms from the same week.
thyroid-function-panel
What this helps clarify: This panel helps frame whether the story fits thyroid slowdown, conversion issues, or a closer competitor cause before you default to broad lifestyle explanations.
Range context
Panel context
How to use the result
Ask which thyroid number best fits the way your fog shows up day to day.
medication-review
What this helps clarify: Medication-related brain fog is often missed because nobody lays the full timeline out in one place.
Range context
Structured medication timeline + risk review
How to use the result
Ask whether a pharmacist-led medication therapy management review is available.
neuropsych-evaluation
What this helps clarify: Gold standard for ADHD and cognitive dysfunction
Range context
Comprehensive testing
How to use the result
Save the result with date and symptoms from the same week.
prolactin
What this helps clarify: Elevated prolactin suppresses testosterone
Range context
2–18 ng/mL (men)
How to use the result
Save the result with date and symptoms from the same week.
Medical Rule-Outs
Before psychiatric diagnosis: thyroid panel, B12, folate, calcium, cortisol, drug screen, CBC, CRP. If presentation atypical or rapid onset: autoimmune encephalitis panel (NMDA-R antibodies), brain MRI, EEG.
What this helps clarify: Before psychiatric diagnosis: thyroid panel, B12, folate, calcium, cortisol, drug screen, CBC, CRP.
Organic rule-outs still worth naming
- •Thyroid disease, B12/folate deficiency, anemia, substance effects, and sleep-disordered breathing can all imitate psychiatric fog.
- •Rapid-onset psychosis, seizures, movement changes, catatonia, fever, or autonomic instability should widen the workup to autoimmune or neurological causes.
- •Older adults need medication toxicity, delirium, and neurodegenerative overlap kept in view.
- •A broad psychiatric label is weaker if the story is mostly positional, meal-linked, post-exertional, or clearly post-infectious.
Questions to ask directly
- •Which diagnosis actually fits best: bipolar-spectrum, PTSD, OCD, psychosis, dissociation, medication burden, or a medical mimic?
- •Does the fog rise with the illness itself, with medication side effects, or with sleep erosion around the episode?
- •What organic rule-outs still matter because the onset was abrupt, age-atypical, or neurologically strange?
- •Would neuropsych testing or a more structured diagnostic interview change management here?
- •Which part needs to move first: safety, sleep stabilization, medication cleanup, therapy, or broader medical workup?
Functional impact snapshot
- -Rate work or school impairment from 1-10
- -Rate relationship strain from 1-10
- -Rate self-care decline from 1-10
- -Note whether the fog episodes line up with mood episodes or stand apart from them
Escalate instead of self-managing if
- •Hallucinations, command voices, or rapidly worsening loss of reality-testing
- •Not sleeping for days with escalating energy, impulsivity, or grandiosity
- •Suicidal thinking, self-harm urges, or violent impulsivity
- •Sudden bizarre behavior, seizures, catatonia, or neurological change
