Hospital 366 Days: Three Weeks of Numbness and the Strokes Already in the Brain (Case No. 9)

⏱ 15 min read

Hospital 366 Days · Case No. 9

The hospital’s year does not end at 365. It runs to 366, and keeps going.

Call him Dave. His age, occupation, location, and identifying details have been changed. The clinical pattern is composite, drawn from the kind of admission that arrives in American emergency departments week after week.

An acute lacunar stroke is typically diagnosed in the emergency department within about one hour. CT scan, thrombolytic decision, neurology consult, the whole sequence wraps up before sunrise. American emergency rooms run that protocol every day.

The patient in this case did not fit that protocol. His CT was clean. More precisely, his CT showed no acute changes. He walked into the emergency department on his own. He gave his date of birth. He remembered his sister’s name. None of his vital signs crossed an emergency threshold.

The imaging showed a different picture at the same hour. Bilateral chronic lacunar infarcts in the basal ganglia. Deep white matter hyperintensities at Fazekas grade 3. Seven deep microbleeds on susceptibility-weighted sequences. Mild atrophy of the left hippocampus. The cumulative vascular burden in his 57-year-old brain matched what radiologists usually read in patients in their late 70s. His MoCA score was below the normal cutoff. He said he had done well on it.

The clinical question for the rest of the admission concerned the chronic lacunar stroke pattern that had accumulated in his brain over two decades. The emergency department had run its protocol on the assumption of a new event. The actual problem was the slow accumulation of small events that had already happened before he reached triage.

This article looks at a case one step before the emergency stage. The case sits in the band where every laboratory value is below an alarm threshold and every laboratory value is outside a normal range at the same time. Clinicians miss this band most often. Families tend to label it “off but not an emergency” and reschedule the appointment. The chart already contains the data on what happens if the same pattern is left alone for another five years.

The Morning His Sister Came Over

At 6:40 a.m. Dave’s sister knocked on the front door of his house. No answer. She used her spare key. Dave was on the living-room sofa, slumped to one side. The TV was on, tuned to an infomercial channel. Four empty beer cans were on the coffee table. Three more were on the floor.

“Dave” is a pseudonym. His age, occupation, family situation, and any other identifying details have been changed. The clinical sequence has been reconstructed from the kind of admission American emergency departments see in repeated patterns and does not represent any single patient.

She called his name. He looked up. He spoke. His words came out slurred. She had been hearing that same slur for the past few weeks. A phone call last Tuesday afternoon. A Sunday lunch the week before. She had assumed at first that he had been drinking. The Tuesday call had been at 2 p.m. on a workday, just before he was supposed to meet a former colleague, and Dave had never been an afternoon drinker.

She told him to stand up. He stood. His left leg dragged. He did not appear to notice. The left corner of his mouth sagged slightly. His forehead moved normally. She held up two fingers. “How many?” He said “two.” Then he smiled. There was nothing to smile about. A minute later his eyes filled with tears and he looked away. Nothing sad had happened. She called 911.

Dave is 57. He worked as an HVAC technician for 35 years and retired five years ago. Divorced, lives alone. Two adult children, both out of state. He has an individual PPO plan and turns Medicare-eligible later this year. His medical history: hypertension (self-reported as controlled, last blood pressure check 18 months earlier), 40 pack-year smoking history with a current habit of one pack per day, chronic alcohol exposure, undiagnosed prediabetes (discovered later in the admission), and untreated dyslipidemia (also discovered later). He denied methamphetamine and cocaine use.

The dragging left leg was the immediate trigger for the 911 call. The harder question, which no one on scene could answer, was how long that leg had been dragging, when his mouth had started to sag, and when the unexplained smiling and crying had begun.

Three Weeks of Symptoms He Did Not Call Symptoms

Here is what his sister was able to reconstruct for the emergency physician once the IV was in.

Three weeks before admission. Sunday lunch. Dave walked slower than usual to the table. She assumed his knee was bothering him. He said his knee was fine. During the meal he dropped a fork once with his left hand. He said the handle was greasy.

Two and a half weeks before admission. Phone call at 1 p.m. on a workday. His speech was thick. She asked if he had been drinking. He said “not yet.” During the call he hesitated for four seconds before saying her name. “Sarah, right.” He had said her name on every call for forty years.

Two weeks before admission. Dave told his sister that his left cheek felt “off.” He said it was not numb, just less responsive than the right side. He thought it might be a dental problem. He did not call the dentist.

Ten days before admission. Family birthday lunch. Dave stood up from his chair and lost his balance once. He blamed the regular lifestyle intake he had with the meal. During the same meal he choked briefly on a sip of water. He coughed for a long time. His teenage nephew said “Uncle Dave, slow down.”

One week before admission. She stopped by. Dave was asleep on the sofa. When he stood up to move to the kitchen, his left hand fumbled briefly on the back of the chair. He said he was still half-asleep. His steps were shorter than normal. His feet barely came off the floor.

Four days before admission. Video call. Dave dragged his left leg as he walked to the kitchen for water. She said “your left leg.” He said “no it isn’t.”

Two days before admission. Text message. He misspelled two short words in a four-line text. She wrote back “you ok?” He wrote back “yep.”

The night before admission. She called. Dave answered. His speech was more slurred than the week before. He was continuing his usual evening habits. At the end of the call he said “where did the remote go?” The remote was on his lap. She decided to drive over first thing in the morning.

Across three weeks, a new symptom showed up roughly every three to four days. Dave attributed each one to a different cause. The dentist. The knee. Metabolic loading. Half-asleep. He never connected the symptoms to a single explanation involving his brain. He was not deceiving anyone. He was only partially aware of the symptoms, the way patients with subcortical brain lesions often are. The phenomenon has a clinical name: anosognosia, the impaired awareness of one’s own deficit. It is common with lesions of the right hemisphere and the bilateral basal ganglia. Patients with that pattern under-report their symptoms. Family reports are often more accurate than the patient’s own answers, and the gap between the two is itself a diagnostic clue.

What the Emergency Department Found, the CT Was “Clean”

Arrival at 7:22 a.m. Triage vitals: blood pressure 152 over 80, heart rate 119, respiratory rate 18, oxygen saturation 96 percent, temperature normal. NIH Stroke Scale 5 (left facial weakness 1, left arm motor 1, left leg motor 1, dysarthria 1, suspected left visuospatial neglect 1).

The Code Stroke protocol was activated. Non-contrast CT within five minutes. Blood draws in parallel.

Non-contrast CT result: bilateral basal ganglia chronic lacunar infarcts (left putamen, right caudate head). Mild chronic ischemic small vessel disease. No acute changes. No hemorrhage.

That one line carried two facts at once. Whatever had happened to this patient over three weeks was not a new infarct visible on CT, so he was not a candidate for thrombolytic therapy. The chronic findings on the same scan showed that the brain had already accumulated several small infarcts over the prior years. The emergency physician moved to the next step.

Laboratory results: white blood cell count normal, platelets normal. Hemoglobin 14.2 normal. MCV 102, just above the upper limit of 100, consistent with macrocytosis. Sodium 133, just below the lower limit of 135 (mild hyponatremia). Creatinine 1.3, approaching the upper limit of 1.2. Magnesium 1.4, below the normal lower limit of 1.7. HbA1c 6.8, in the prediabetes-to-early-type-2 range. LDL 156, well above the target of under 100. AST 56 with ALT 38, a pattern consistent with long-standing alcohol exposure; GGT 312, roughly six times the upper limit. INR 1.2, slightly elevated.

ECG: sinus tachycardia at 119. Left ventricular hypertrophy pattern. No other acute findings.

Chest X-ray: normal.

At this point the emergency physician reread the chart from the top. A 57-year-old man with three weeks of progressive left-sided sensory and motor symptoms, a left leg drag for several days, weeks of slurred speech, family-reported emotional lability, a 40 pack-year smoking history with continued use, severe alcohol use disorder status, a CT showing only chronic bilateral lacunar infarcts and chronic small vessel disease, undiagnosed prediabetes, untreated dyslipidemia, the GGT and MCV pattern of chronic alcohol exposure, low magnesium, and resting tachycardia at 119.

The physician entered the consult board: Neurology consult. Bilateral chronic lacunar infarcts with progressive symptoms over three weeks. MRI brain with diffusion. Cognitive evaluation. CIWA-Ar protocol initiation. IV thiamine before glucose. Magnesium and folate replacement. Withdrawal precautions, telemetry monitoring.

The orders the emergency department wrote were not for a thrombolytic. They were for a withdrawal prevention protocol, vitamin replacement, and admission to neurology. “Clean CT” meant two things at the same time: no new stroke this morning, and a brain that had already accumulated several years of small strokes that were not identified when they happened.

The MRI six hours into the admission quantified the second meaning. DWI showed no acute restricted diffusion, confirming the emergency-department read. FLAIR showed multiple chronic lacunes in the bilateral basal ganglia, bilateral thalami, and pons. Periventricular and deep white matter hyperintensities reached Fazekas grade 3, which is the imaging burden typically seen in patients in their late 70s. Dave is 57. SWI sequences identified seven deep microbleeds across both basal ganglia and thalami. The left hippocampus showed mild atrophy.

The MoCA was administered that afternoon. Dave scored 19 out of 30. Scores under 26 indicate cognitive impairment; scores at or under 17 are used as a clinical adjunct for vascular dementia diagnosis. His deficits clustered in executive function: trail making, abstraction, verbal fluency. His orientation was intact. His short-term recall was two out of five. He said he had done well on the test.

Every one of Dave’s numbers was below an emergency threshold. Every one of Dave’s numbers was outside a normal range. Those two sentences hold true at the same time. The case occupies that band.

How a Lacunar Stroke Pattern Builds for Years Before the First Symptom

Deep inside the brain, the arteries that feed the basal ganglia, thalamus, internal capsule, and pons are very small. They are penetrating arterioles, roughly 100 to 400 micrometers across, with almost no branching. They deliver blood to a defined territory with no collateral backup. When one of these arterioles closes, the territory it supplied becomes ischemic within minutes. An MRI captures the result later: a small lesion under 15 millimeters across, called a lacune.

Two mechanisms close these small arteries. Lipohyalinosis is the slow thickening and luminal narrowing produced by chronic hypertension acting on the vessel wall. Microatheroma is atherosclerotic plaque forming inside the same small vessel or at its origin. Both take years to develop. Both can produce a lacunar stroke when one finally occludes a vessel completely.

In the United States, the annual incidence of lacunar stroke is around 13 to 20 per 100,000, depending on the community study, and lacunar events account for roughly 15 to 25 percent of all ischemic strokes, according to StatPearls 2024 and the long-running Mayo Clinic Rochester population study. Hypertension is present in 81 percent of lacunar stroke patients, far higher than for any other stroke subtype. The patient profile skews male and middle-aged at first stroke, then older over time.

Dave’s MRI showed multiple chronic lacunes across both basal ganglia, both thalami, and the pons. Each lacune was a separate small event at some point in the prior years. When each one happened, Dave may have called it a bad night’s sleep, a stiff back, or a long day. Family may have heard the same explanations. One at a time, the events went unrecognized. The MRI showed all of them together, on one image.

The Fazekas grade 3 reading was the scan’s second key finding. A 2020 study of 321 non-demented community adults identified Fazekas grade 3 as the critical imaging stage predicting future cognitive decline. The 2025 SAGE-AF cohort reported a 2.6-fold higher risk of cognitive impairment and a 2.7-fold higher risk of frailty at two years in patients with Fazekas grade 2 to 3 disease.

The seven microbleeds were the third piece. In the SPS3 trial of 1,278 lacunar stroke patients, cerebral microbleeds were associated with an adjusted 2.1-fold increase in recurrent stroke risk. Above five microbleeds the risk increases more steeply.

Taken together, what the imaging showed about Dave’s brain was straightforward. The imaging had already identified the locations most likely to be the site of the next event.

40 Pack-Years and Severe Alcohol Exposure, Two Slow Hands

Pack-years are the standard cumulative measure of tobacco exposure. One pack per day for 40 years equals 40 pack-years. Two packs per day for 20 years also equals 40 pack-years. Dave had reached 40 pack-years. At his current pace he was adding one more pack-year per year.

Smoking accelerates cerebral small vessel disease. A 2025 iRADIOLOGY review identified smoking as a major initiating factor for white matter hyperintensities, with longer smoking duration tracking directly with greater WMH progression. The mechanism is established. Smoking produces endothelial dysfunction, oxidative damage to the small-vessel intima, and faster atherosclerosis. Small vessels respond fastest because they have the least reserve.

Alcohol reaches the same outcome through different mechanisms. Daily heavy intake raises blood pressure over time, and high blood pressure is the leading driver of the lipohyalinosis pattern that closes small cerebral arteries. The World Stroke Organization attributes more than half of all strokes to hypertension, and daily alcohol consumption is one of the consistent drivers of that hypertension. At Dave’s level of intake, a 2010 systematic review and meta-analysis reported a relative risk of 2.52 for hemorrhagic stroke morbidity in men presenting advanced consumption metrics, and 1.94 for hemorrhagic stroke mortality across prolonged clinical windows.

Alcohol acts on the brain through a second pathway: atrial fibrillation. Chronic daily exposure raises the incidence of paroxysmal AF, and AF independently multiplies stroke risk by roughly five times.

The combined risk profile in Dave’s chart includes four exposures: 40 pack-years of tobacco, severe alcohol use disorder history, untreated dyslipidemia at LDL 156, and undiagnosed prediabetes at HbA1c 6.8. The 2021 Journal of Stroke and Cerebrovascular Diseases meta-analysis identifies smoking, hypertension, diabetes, atrial fibrillation, prior stroke, and stroke severity as independent predictors of stroke recurrence. Dave matches on five of those six. The same pair of risk factors, smoking and chronic alcohol exposure, can affect a different organ entirely; another case in this series follows the same pair into the upper airway.

What Vascular Cognitive Impairment Actually Means

Vascular Cognitive Impairment (VCI) is the umbrella term covering the entire range of cognitive consequences of cerebrovascular disease. The mild end is called vascular cognitive impairment, no dementia (VCIND). The severe end is vascular dementia (VaD). They sit on a continuum.

Alzheimer’s disease progresses differently. The curve is gradual and steady. Memory tends to be the earliest domain affected.

VCI moves in steps. Each new infarct reduces cognition by one step. Between events, the patient often reports feeling fine. The next event reduces the level again. The cognitive domain affected first is executive function: bill paying, medication management, driving judgment, following a complicated conversation. Memory frequently stays relatively intact until later, which is one of the reasons VCI gets recognized late. Families typically watch for memory loss as the signal. By the time memory finally declines, executive function has been impaired for a long while. The NINDS-CSN Vascular Cognitive Impairment Harmonization Standards selected the MoCA as the preferred screening tool partly because it weights executive function tasks more heavily than the older MMSE.

The standard MoCA interpretation runs as follows: 26 and above is in the normal range, 18 to 25 suggests mild cognitive impairment, and 17 and under serves as an adjunct cutoff for vascular dementia diagnosis with sensitivity around 77 percent and specificity around 97 percent (Freitas 2012 validation).

Dave’s 19 falls in the VCIND range. Patients at this stage usually preserve basic ADLs (dressing, feeding, toileting) but begin to have trouble with complex IADLs: bills, prescriptions, transportation logistics, appointment tracking. The earliest external signals families pick up are repeated questions, missed appointments, overdue notices, and trouble retrieving common words. From this point, if the four cerebrovascular drivers continue unaddressed, the rate of progression is faster than the natural aging curve. The 2020 Shanghai Aging Study seven-year follow-up showed that participants with higher baseline WMH burden accumulated additional lacunes, additional microbleeds, and faster executive-function decline at a measurably higher rate. A 442-patient population-based series reported a 25 percent five-year recurrence rate among lacunar stroke patients. For a profile that includes multiple chronic lacunes, Fazekas grade 3, seven microbleeds, and four uncontrolled drivers, that 25 percent is closer to a floor than an average.

The Withdrawal Problem That Starts on Day One of Admission

Dave arrived at the emergency department about four hours after his last consumption milestone. Over the next 24 hours, autonomic withdrawal risk would reach its highest level.

The standard alcohol withdrawal timeline runs as follows. Minor withdrawal (tremor, tachycardia, diaphoresis, anxiety) starts at six to twelve hours after the last drink. Withdrawal seizures occur in up to 15 percent of severe AUD patients, peaking at 12 to 48 hours, per StatPearls 2024. Alcohol hallucinosis can appear in the same period. Delirium tremens develops in 3 to 5 percent of withdrawal cases, peaking at 48 to 96 hours, per Cleveland Clinic. Treated DT mortality is 1 to 5 percent. Untreated, the published range is 15 to 50 percent.

The baseline history corresponds to severe alcohol use disorder status, tracking significantly above standard toxic exposure limits. The admission protocol for a patient at this level is standard. CIWA-Ar scoring every four hours, with a target of under 8. Symptom-triggered benzodiazepines, usually lorazepam or diazepam. Intravenous thiamine 100 milligrams given before any glucose. Replacement of magnesium, folate, and a multivitamin. Telemetry monitoring through the autonomic risk period.

The thiamine-before-glucose rule has a specific physiological basis. A patient with chronic alcohol exposure is severely thiamine-depleted. If intravenous glucose reaches the brain first, thiamine-dependent metabolic pathways accelerate, the residual thiamine is consumed quickly, and the patient can develop Wernicke encephalopathy (confusion, ataxia, ophthalmoplegia). Untreated Wernicke progresses to Korsakoff syndrome, an essentially permanent failure to form new memories. In a patient who already has measurable cognitive impairment, a Korsakoff event drops independence by two steps rather than one.

The note IV thiamine before glucose on the emergency board took 30 seconds to write. It may determine whether this patient still recognizes his sister five years from now.

Two Costs, One Decision Window

The dollar gap is not what makes the comparison meaningful. A patient with a PPO plan pays up to the out-of-pocket maximum either way. What matters is time. Across the three weeks before admission, the chronic small vessel disease was continuing to add new candidate sites for future events, and the alcohol-driven autonomic and metabolic load was continuing unchecked. Starting the same workup a year earlier would not have changed Dave’s accumulated brain damage. It would have changed the trajectory of his next five years.

Dave is scheduled for discharge on the fourth hospital day with a neurology follow-up appointment. The five decisions in front of him during the week after discharge are these. Whether to accept a smoking cessation referral. Whether to start outpatient alcohol use disorder care. Whether to fill the statin prescription. Whether to begin daily home blood pressure measurement. Whether to spend 30 minutes with a neurologist on the antiplatelet decision.

None of those five decisions belongs to the emergency department. The emergency department confirmed that Dave could walk out of the hospital. The next five years are decided outside the emergency department. How Dave answers each of those five decisions becomes measurable data starting the week after this admission.

The accumulation of the past twenty years cannot be reversed. The next five years can be reshaped. The same sentence applies to Dave and to every 57-year-old man who recognizes his own situation in this case.
