When "Sudden Madness" Was Actually a Stroke: A 60-Year-Old Man's Ten-Day Journey to the Right Diagnosis
Dr. Dharmin Shah31 July 2026

A family watched a healthy 60-year-old man turn restless, disoriented, and hostile within days of a fever — and were told it was a psychiatric breakdown. The real cause was sitting quietly on an MRI: a large right-hemisphere stroke that had gone completely unrecognized.
It started, as these things often do, with something that seemed almost trivial: a fever.
The patient, a 60-year-old man with no prior psychiatric history, had been entirely his usual self until then — going about his day, recognizable to everyone around him. Within a short window after the fever, his family noticed he wasn't quite right. He became disoriented. He couldn't settle. He started wandering from room to room, unable to stay in one place. He grew insomniac, forgetful, and at times hostile — even toward his wife, the person trying hardest to help him.
To anyone unfamiliar with the neurology of acute brain injury, this looks like a psychiatric emergency. And that is exactly how it was initially treated.
The first ten days
The family took him to a local physician, where he was admitted and given a course of intravenous infusions — the exact composition of which was never documented, so we have no clear record of what he received. Blood work at the time showed a raised CRP and elevated blood sugar, which was managed with metformin and glimepiride.
On the psychiatric side, he was started on a combination that should raise eyebrows for anyone trained in geriatric or neuropsychiatry: citalopram, clonazepam, olanzapine, and risperidone — four psychotropic agents, layered on top of each other, in a man whose actual underlying problem had not yet been identified. There was no documented neuroimaging at this stage. The working assumption, understandably but incorrectly, was that this was a primary psychiatric decompensation.
Ten days in, with no real improvement, the family brought him to us.
What the exam actually showed
The behavioral picture on presentation was distinctive in a way that should always prompt a neurological workup rather than a purely psychiatric one:
Restlessness and an inability to stay in one place — wandering, not agitation in the classic psychiatric sense
Disorientation to place, while time and person recognition remained intact
Insomnia
Episodes of hostility directed at his primary caregiver
Urinary incontinence
Forgetfulness and cognitive impairment
Inability to follow instructions or commands
Difficulty identifying objects
That last cluster — command-following difficulty and object identification trouble, alongside place-specific disorientation — is not a typical psychiatric symptom profile. It's a pattern that points toward a focal, lateralized brain lesion, particularly involving the right hemisphere's role in spatial orientation and attention.
The investigation that changed everything
Repeat blood work showed a WBC count of 11,000, an elevated HbA1c confirming true diabetes rather than a transient stress hyperglycemia, and a CRP of 5 — mildly raised, not the dramatic infective picture the earlier treatment seemed to assume.
The MRI brain, however, told the real story. It showed a large confluent area of acute-to-subacute, non-hemorrhagic infarction with cortical laminar necrosis in the right frontal lobe and right insular operculum — essentially, a substantial stroke affecting a region of the brain deeply involved in attention, behavior regulation, and spatial awareness. There were additional small, discrete acute infarcts in the right occipital lobe, along with mild age-related cerebral and cerebellar atrophy.
Vascular imaging explained why: loss of normal flow signal in the distal M2–M3 segments of the right middle cerebral artery, moderate-to-severe atherosclerotic narrowing in the distal cervical right internal carotid artery, and a hypoplastic right vertebral artery throughout its course — a combination that left the right MCA territory vulnerable to exactly this kind of infarction.
In short: this was never a primary psychiatric illness. It was a right-hemisphere ischemic stroke, and everything the family had been describing — the wandering, the disorientation to place, the hostility, the incontinence, the cognitive decline — was the neuropsychiatric signature of that stroke.
Reassessing and managing the case
Once the vascular cause was clear, management shifted in three directions simultaneously.
First, the medication list needed urgent reconciliation. Four psychotropic agents started empirically, without a clear diagnosis or imaging, is a recipe for oversedation, further confusion, and fall risk — particularly in a patient with an acute stroke and an undiagnosed vascular risk profile. These were tapered and rationalized, keeping only what was clinically justified for symptom control, at the lowest effective doses.
Second, this became a joint neurology-psychiatry case rather than one being managed by either specialty in isolation. The vascular risk factors — significant carotid disease, newly confirmed diabetes with an elevated HbA1c, and the imaging evidence of ongoing ischemia — needed active secondary stroke prevention: antiplatelet therapy, statin optimization, tight glycemic control, and vascular risk counselling, alongside neurological monitoring for further ischemic events given the degree of ICA narrowing.
Third, the neuropsychiatric symptoms — the agitation, the disorientation, the sleep disruption — were treated as what they were: a post-stroke confusional and behavioral syndrome, not an independent psychiatric disorder. This meant a calmer, lower-dose approach to symptom management, environmental measures to reduce disorientation (consistent routines, family presence, orientation cues), and close monitoring for evolving vascular cognitive impairment rather than reflexive escalation of psychiatric medication.
Family counselling was equally important here. The wife, who had borne the brunt of his hostility, needed to understand that this behavior was neurological in origin — a product of frontal and right-hemisphere injury — not a personal rejection or a psychiatric breakdown. That reframing alone often changes how a family copes with and supports a patient through recovery.
Why this case matters
This case is a reminder of something we see more often than we'd like in general practice: an acute confusional or behavioral presentation, especially in an older adult with vascular risk factors, deserves neuroimaging before it is labelled psychiatric. A fever followed by sudden disorientation, wandering, and personality change is a red flag for a neurological event — stroke, encephalitis, or otherwise — not a reflex indication for antipsychotics and benzodiazepines.
For families watching a loved one change seemingly overnight, the message is simple: sudden confusion is a medical emergency until proven otherwise. Getting the right imaging early can be the difference between ten days of the wrong treatment and a diagnosis that actually explains — and treats — what's happening.
