Kasi Vishwanadham — Medical Overview

Where things stand now

The essentials for a clinician meeting him for the first time.

Core diagnoses

Schizophrenia+ drug-induced Parkinsonism + nutritional (peripheral) neuropathy, NCS-confirmed

Current baseline

Mostly stuckImmobile ~80%+ of the time; roughly one good (walking) day every ~5–6 days. Walking days are the exception.

Working diagnosis

Cyclical psychosisThe psychosis comes and goes in cycles. Clinically: drug-induced periodic catatonia / iatrogenic dopaminergic oscillation — his brain's dopamine system swinging on and off after 20+ years of antipsychotic medicines.

Highest-value test

Lorazepam challengeThe single most informative test if he stays stuck — supervised, during a stuck phase (easy to time). Sits after the current 4–6 week pimavanserin trial.

Current medication regimen — early July 2026
Medicine	Dose & timing	Status	Role
Quetiapine	100 mg · twice daily	Taking	Low, maintenance-level antipsychotic; relatively Parkinson's-safe (corrected 9 Jul — twice daily, not once)
Levodopa / Carbidopa (LCD)	110 mg	Taking	Dopamine replacement for Parkinsonism (confirm daily schedule — prior was 3×/day)
Pimavanserin	34 mg · night	Taking	A newer antipsychotic (5-HT2A inverse agonist) that calms psychosis without blocking dopamine — so it doesn't worsen the stiffness/slowness. Added when aripiprazole was stopped (30 Jun). Independently recommended by two psychiatrists (Dr. Virinchi Sharma and Dr. Jyothirmayi, Manaha Clinic)
Vortioxetine	5 mg · night	Not taking	Prescribed for pain (serotonergic modulation) but not actually being taken
Aripiprazole	was 5 mg	Stopped	The high-D2-occupancy "clamp"; discontinued 30 Jun 2026. Briefly restarted for a couple of days in early-mid Jul 2026, then stopped again — not continuing

Background / standing medicines: Vitamin B12 injection (Meaxon) weekly · Vitamin D3 60 K weekly · Carniglo-M (L-carnitine + B12) · Gabapentin 300 mg at night (widely noted as under-dosed for neuropathy — daytime cover is a gap). The 30 June change moved the regimen decisively toward less dopamine blockade while keeping antipsychotic cover — the direction earlier analysis recommended.

The pivotal observation: two tracks, mostly overlapping

When Nanna is at his worst, immobility, pain, delusion and hallucinations appear together — which first looked like one single problem. But a key refinement (10 Jul): the immobility can occur on its own, with no psychosis at all — and that is his commonest stuck state. So it is better read as a baseline movement problem with an on-and-off psychosis layered on top.

Stuck phase

Default state · ~80%+ of days

Immobile — cannot rise from lying or sitting; pain on any attempt to move
Pain at rest too — not only on movement (a July 2026 change)
"Electric fields" delusion — believes someone is sending fields to cause the pain (a somatic passivity delusion — a false belief that an outside force is controlling his body)
Hallucinations — both visual and auditory, present in this phase
Shouts at his persecutors; afterwards the "field" and pain ease

Walking phase

Exception · ~1 day in 5–6

Walks fully & normally — to the supermarket, sustained for hours
No rest pain — pain is entirely absent
No delusion — the electric-fields belief is gone
No hallucinations — visual and auditory both absent
His own words: "when the connection is cut, I have no problems"

Why the pain is not a separate physical problem

Whenever pain is present it tracks the delusion — he attributes it to the electric fields, it eases when he shouts at the hallucinated attacker, and it vanishes entirely on well days. That is not behaving like tissue pain — it behaves as part of the psychotic layer. Recovery is reliably preceded by a night of prolonged self-talk (a prodrome), suggesting an endogenous surge that periodically breaks the state. Further structural / orthopaedic work-up is low-yield. Note the pain rides with the psychosis; the immobility is a separate track that is often present on its own (see below) — so the leverage is partly psychiatric and partly on the movement/catatonia side.

Refinement · 10 Jul 2026 — it's not all one switch

A closer look shows the immobility and the psychosis are separable. There are really three states, and the most common "stuck" state has no psychosis in it at all:

State	Movement	Psychosis	Pain	How often
Stuck, no psychosis	Stuck	None	Probably none (unconfirmed)	Most common stuck state
Full bad phase	Stuck	Electric-fields delusion + hallucinations	Present	Less frequent
Good phase	Walks normally	None	None	~1 day in 5–6

Two consequences. (1) The "stuck" state is not just a symptom of the psychosis — it has its own driver, which is exactly what a catatonic or a Parkinsonian "off" state looks like. That makes the lorazepam test more important, and means a stronger antipsychotic alone would not be expected to release the stuck state. (2) Pain still travels with the psychosis — whenever he has pain, he attributes it to the electric fields — so pain marks the psychosis layer, not the movement layer.

A witnessed episode · 10 Jul 2026

During a stuck-phase pain episode, Nanna said the pain was coming as "waves through the air cooler", and was shouting and swearing to drive off the imaginary people causing it — now believing his wife was helping to instigate them. Telling him she was simply in the bathroom, and then moving the air cooler out of the room, calmed him down and the pain settled.

Two things stand out. The belief has attached to a specific object (the cooler as a "wave emitter") and now names a family member as a co-conspirator — both signs of active, not-fully-controlled psychosis. And once again the pain eased through calming and removing the object, not a painkiller — more evidence it tracks the belief, not tissue damage. Gentle reassurance plus removing the fixated-on object de-escalated him without confrontation — a useful caregiving approach, though whether to keep accommodating the delusion this way is worth raising with the psychiatrist.

How the diagnosis converged

The working picture arrived by ruling things out — the spine and soft-tissue leads were investigated and demoted before the neuropsychiatric model emerged.

Mar 2026 · crisis

Couldn't get up for 2 days

Followed a 15-month gap off all medicines. Resolved with levodopa + B12 — a physical, dopamine-deficiency crisis, before antipsychotics were restarted.
Apr–May 2026 · spine lead

Lumbar MRI → stenosis at L3–L4

Real degenerative findings. But 3 of 4 specialists (incl. the treating neurologist and a UK MSK radiologist) read them as background age-related change — not enough to explain being bedbound while also walking to the shops other days.
May 2026 · soft-tissue lead

A "sitting-bone" inflammation idea

Ischiogluteal bursitis — inflammation where the body meets a chair — fit the "can't rise" pattern for a while. Then broken by three findings: recovery was always preceded by a night of talking (a warning sign a pure muscle problem can't explain), reducing crawling didn't help, and pressing the sore spot didn't reproduce the pain.
17 May 2026 · the pivot

A medicine-driven brain cycle

Everything switching on and off together, fully clearing on good days, in a brain made over-sensitive by 20+ years of antipsychotics — a "periodic catatonia" type picture. (iatrogenic dopaminergic oscillation)
Jul 2026 · direct confirmation

The delusion + hallucinations surfaced

The electric-fields somatic delusion and the visual + auditory hallucinations — present only in stuck phases — are the first directly observed active psychotic symptoms, corroborating the model rather than inferring it.
9 Jul 2026 · confirmed

Rest pain is zero on walking days — no exception

Rest pain (below the buttocks) can occur without auditory hallucinations at that moment — it's driven by the electric-fields delusion on its own, not dependent on voices. But during walking (good) days he has no pain at all, including at rest — closing the question of whether a separate physical pain source might run in parallel. Rest pain is 100% confined to stuck phases, same as the delusion.

The mechanism, in short

Two decades of antipsychotics blunted his brain's dopamine signals, so the system became over-sensitive to compensate. On top of that, aripiprazole acted like a "clamp" holding the dopamine receptors shut — one the over-sensitive brain kept straining against. Every so often the brain's own surge breaks through the clamp (seen as the night-talking), and he has a good day. (Clinically: D2 supersensitisation with an iatrogenic dopaminergic oscillation.)

Why extra levodopa doesn't rescue a stuck phase: the bottleneck is receptor occupancy by the antipsychotic, not a shortage of dopamine — so more levodopa can't push past an already-occupied receptor. Stopping aripiprazole (done 30 Jun) directly tests this.

Specialist reads on the spine question
Voice	Verdict
Dr. Neehar (treating neurologist)	Disability disproportionate to pathology — primarily psychiatric; see a psychiatrist
Dr. Sudhakar (UK MSK radiologist)	Mild, age-appropriate changes; not surgical
Original MRI report	Findings listed; "correlate clinically" (hedged)
Rakesh (ortho surgeon, informal)	Initially surgery; later revised — "if he can walk to the supermarket, it's not primarily the spine"

Other possibilities still on the table

The cyclical model is the leading one, but it isn't the only disease that can produce this picture. These are the alternatives worth keeping in mind — and the tests that would tell them apart. The strongest constraint is that everything switches on and off together; very few conditions do that, which is what narrows the list.

Tier 1 · best fits for the all-or-nothing cycle

Leading — already the working model

Periodic catatonia / drug-driven dopamine oscillationA rare schizophrenia pattern of recurring "frozen" episodes alternating with near-normal spells, on a brain made over-sensitive by 20+ years of antipsychotics. Not one diagnosis vs another — these overlap. Test: lorazepam challenge.

Take more seriously

Lewy body diseaseParkinsonism + recurrent visual hallucinations + big day-to-day fluctuations is the classic triad — and "fluctuation" can look just like good and bad days. What's called drug-induced Parkinsonism could be underlying Lewy pathology unmasked by the medicines. Test: DAT-SPECT scan.

Physiological pain that still fits the cycle

Levodopa "off-period" effectsIf there's real dopamine-system degeneration underneath, stuck phases could be "off" states — including off-period dystonia, a genuine cramping leg pain that cycles with the motor state. This would make some of the pain real tissue pain, not delusion — and the two can coexist. Test: does a stuck phase break within ~1 hr of a levodopa dose?

The current live experiment

Iatrogenic oscillationThe idea that stopping aripiprazole (done 30 Jun) should ease the cycling. The coming weeks are the test — keep the daily walked/talked log running as the outcome measure.

Tier 2 · physiological contributors that could ride on the cycle

Silent recurring triggers of confusion (delirium) — a hidden urine infection, constipation, dehydration swings, or night-time drops in oxygen from sleep apnoea (which would also fit the night-talking). Cheap to screen: urine test during a bad phase, overnight oxygen check.

Non-epileptic brain "arrest" episodes — a form of epilepsy that causes behavioural freezing rather than convulsions; the March EEG can miss it. Test: repeat EEG during a stuck phase.

B12-deficiency brain/nerve disease — 15 months unsupplemented can cause psychosis and worse neuropathy. The earlier B12 result was falsely high. Test: MMA + homocysteine (the true B12 status).

Swinging body chemistry — thyroid, sodium, calcium, kidney values checked during a bad phase vs a good one. A value that repeatedly swings is one of the few things that genuinely produces on/off days.

Tier 3 · rare, but each a single cheap rule-out

Autoimmune encephalitis — the one rare disease that naturally produces psychosis + catatonia + movement problems + pain together and fluctuates; usually comes on over weeks (the March crash qualifies). One blood panel. · Neurosyphilis / HIV — old-fashioned, cheap rule-outs for late-life psychosis, likely never tested. · Paraneoplastic syndrome (a hidden cancer driving the nerve + brain picture) — only if the above come back clean. · Normal-pressure hydrocephalus — gait + memory + urinary, but it doesn't cycle; low probability.

What discriminates fastest — the test-priority ladder

1. Lorazepam challenge in a stuck phase (already planned) — separates catatonia from everything else in an afternoon. 2. Levodopa-timing vs stuck-phase diary — free; tests the "off-state" idea. 3. DAT-SPECT — drug-induced vs Lewy-body Parkinsonism; decides whether the levodopa lever or the antipsychotic lever is the main one. 4. One "bad-phase" blood/urine panel — sweeps Tier 2 in a single draw. 5. Autoimmune / syphilis / HIV serology — sweeps Tier 3 if 1–4 are unrevealing.

Bottom line: the top three of these aren't rivals so much as layers — a supersensitised, partly degenerated dopamine system swinging between "off" (stuck + cramping pain + psychosis) and "on" (walking, clear) would unify almost everything, with periodic catatonia as the main structural alternative. The lorazepam challenge plus the levodopa-timing diary should reveal which world we're in within a couple of weeks, at essentially no cost or risk.

The forward plan

A staged path to discuss with the prescriber if pimavanserin proves too weak. Not a prescription — every step is a physician's decision.

To raise with Dr. Virinchi

The electric-fields somatic delusion, and that pain / immobility / delusion cycle together
That walking days are completely symptom-free
That both visual and auditory hallucinations are present — raise levodopa as a possible contributor
Whether current cover (pimavanserin + low quetiapine) is enough given florid symptoms in stuck phases
A baseline ECG (pimavanserin can prolong QT)
Decide whether to start or formally drop vortioxetine; confirm the LCD schedule

Reading the 4–6 week pimavanserin trial

Psychosis ↓ + pain ↓ + walking returns → unified model correct; may need no escalation.

Psychosis ↓ but still stuck → the catatonic motor component isn't responding to an antipsychotic → go to the lorazepam route.

No change → pimavanserin too weak → escalate up the ladder.

Escalation ladder

Lorazepam / benzodiazepine — the first escalation, not a fallback

The immobility looks catatonic, and catatonia responds to benzodiazepines, not stronger antipsychotics. Confirm with a supervised lorazepam challenge during a stuck phase; if positive, scheduled lorazepam as treatment. Does not worsen Parkinsonism.

Uptitrate quetiapine

Lowest-friction antipsychotic step — already on it, relatively Parkinson's-safe, no new drug or monitoring. Watch sedation / falls; only moderate potency.

Clozapine

The one strong antipsychotic that controls psychosis without worsening movement — but needs regular blood monitoring, carries fall/sedation risk, and interacts with lorazepam (additive CNS/respiratory depression — don't start simultaneously). Specialist decision.

Add valproate

If the defining problem is the periodicity, valproate targets the cycle directly, with no dopamine blockade — an adjunct, not a standalone antipsychotic.

ECT — for refractory cases

Highly effective and specifically indicated for both catatonia and severe psychosis; in a frail elderly patient often safer than stacking sedating drugs. Reserved, but a genuine option.

The single most important "don't"

Avoid high-potency, strong D2-blocking antipsychotics — haloperidol, higher-dose risperidone or olanzapine. In someone with drug-induced Parkinsonism and a catatonic component, these both worsen the stiffness/slowness (the 20-year trap that started all of this) and risk triggering a rare, dangerous reaction (malignant catatonia / neuroleptic malignant syndrome). Flag this to any new doctor who, seeing severe psychosis, might reach for a strong older antipsychotic.

Diagnoses in full

Schizophrenia — long-standing (20+ years), well-controlled for most of that time on antipsychotic medicines (quetiapine / flupenthixol). Right now the symptoms (delusions, hallucinations) are active during the stuck phases.
Drug-induced Parkinsonism — stiffness and slowness caused by those same long-term antipsychotics; it improves with levodopa.
Nutritional nerve damage in both legs (peripheral neuropathy) — confirmed by nerve tests in Nov 2022 and worse by Dec 2024. Not from diabetes (blood sugar is normal); linked to vitamin deficiency.
Cyclical psychosis — the current best explanation tying the immobility, pain, delusion and hallucinations into one problem (see sections 2–3).

Other findings noted along the way: poor balance (Romberg's positive), some involuntary body-function irregularity (autonomic dysfunction), and one slightly low thyroid value (low T3). A blood-pressure reading of 145/102 (high) appears on prescriptions and was never acted on — but family says some readings were copied over from a template, so it needs a fresh, real measurement. No day-to-day memory loss seen at home.

Timeline of crises & prescription changes

Dec 2024 → Mar 2026 — he was off all medicines for about 15 months (levodopa, B12, vitamin D, nerve medicines, and antipsychotics). Telling detail: he went those 15 months with no antipsychotic and did not have a psychiatric breakdown.

18 Mar 2026 — crisis — couldn't get up for 2 days; levodopa + a B12 injection got him moving again. Video consult with Dr. Neeraja Alluri.

25 Mar 2026 — put on three antipsychotics at once (olanzapine + quetiapine + risperidone) — too much, and it drove the next crisis.

30–31 Mar 2026 — immobile again from too much dopamine blockade; the family stopped risperidone and he walked within 9 hours. Care moved back to Dr. Neehar, who simplified to a single antipsychotic (aripiprazole 5 mg) plus gabapentin and B12.

Apr–May 2026 — discovered his levodopa was being given wrong (twice a day, after food, instead of three times before food) and corrected it; the spine and muscle leads were investigated and set aside; care was briefly remote-only with Dr. Sudhakar (UK).

30 Jun 2026 — Dr. Virinchi Sharma (psychiatrist): stopped aripiprazole and added pimavanserin 34 mg; also prescribed vortioxetine (not being taken). This is the current shift toward less dopamine blockade. A second psychiatrist, Dr. Jyothirmayi (Manaha Clinic), independently recommended the same pimavanserin 34 mg.

Key investigations on record

Nerve tests (NCS / EMG) — Nov 2022 & Dec 2024: confirmed nerve damage in both legs, worse on the second test.

Brain wave test (EEG) — 25 Mar 2026: some abnormal electrical activity in the front/side of the brain, but not epilepsy; no seizure medicine needed.

Lower-back MRI scan — 6 May 2026: several age-related wear-and-tear changes, the main one a narrowing at the L3–L4 level pressing on nearby nerves. Most reviewers read these as normal-for-his-age background changes, not the cause of his disability.

Blood tests — the B12 result was falsely high because it was taken just after a B12 injection (a truer test is still pending); slightly low thyroid (T3); mild anaemia (low haemoglobin, 12.2).

Useful tests not yet done: the lorazepam challenge; a prolactin blood test during a stuck day vs a good day; a baseline heart-rhythm check (ECG, for the new medicine); a repeat nerve test; and the fuller B12 tests.

Care team

Clinician	Role	Status
Dr. Virinchi Sharma	Psychiatrist — current prescriber (30 Jun 2026); prescribed pimavanserin 34 mg	Current
Dr. Jyothirmayi	Psychiatrist, Manaha Clinic — independent second opinion; also recommended pimavanserin 34 mg	Concurring
Dr. Neehar Potluri	Brain & nerve specialist (neurologist) — examined him in person over the longest period; view: "this is primarily psychiatric — see a psychiatrist"	Prior / key
Dr. Neeraja Alluri	Brain & nerve specialist (neurologist) — Mar 2026	Discontinued
Dr. Sudhakar	UK bone/joint imaging specialist — reviewed scans remotely	Consultant
Rakesh	Orthopaedic surgeon — informal home review	Informal

A recurring recommendation in the record: find a trusted local doctor (a general physician or a specialist in elderly care) to be the on-the-ground prescriber who examines him and orders tests — several things (medicine changes, blood monitoring, any next step) can't be handled from a distance.
