Memory and word-finding
Names slip. Sentences trail off. You walk into a room and forget why. Working memory is one of the most commonly impaired domains after TIA.2
Your TIA was supposed to be temporary. Why doesn't your brain feel like it?
A TIA resolves within 24 hours. Cognitive symptoms don't follow that timeline. At Cognitive FX, we treat the brain fog, fatigue, and processing slowness that standard care leaves behind.

Cognitive recovery after a TIA isn't automatic
A TIA is over within 24 hours by definition. Cognitive recovery is not. This is what longitudinal research shows happens in the first 90 days across the four most commonly affected domains.

Still struggle with executive function at day 90
Planning, multitasking, and switching between tasks. The slowest domain to recover and the one most disruptive to work and driving.
Day 60-120
The plasticity window most patients miss
The CPASS trial confirmed brains are most receptive to rehabilitation in the first 60-120 days post-event. Standard care rarely uses this window.
Recovery is faster when you target it
The curves above describe what happens with usual care. Targeted, intensive rehabilitation during the plasticity window changes the trajectory. That is the entire point of the EPIC program at Cognitive FX.
After the Event
The symptoms that stay behind
"Transient" describes how long the original event lasted. It does not describe how long the effects can last. Research consistently shows TIA and minor stroke patients carry a real symptom burden long after the ER discharge papers are signed.
Slower processing
Conversations feel faster than they used to. Reading takes longer. Information processing speed drops measurably in roughly 1 in 6 patients within three months.2
Attention and focus
You lose the thread of meetings. Background noise feels louder. About 1 in 5 TIA patients show attention deficits compared with healthy peers.2
Persistent brain fog
A heavy, slow feeling that doesn't lift. Subjective cognitive complaints are common after TIA and tend to track with reduced quality of life.4
Unexplained fatigue
You sleep but don't feel restored. Post-TIA fatigue is well documented and often correlates with mood symptoms and difficulty returning to work.5
Anxiety and low mood
Roughly 29% of TIA patients show clinically meaningful anxiety symptoms; roughly 24% show depressive symptoms.6 Fear of another event drives much of it.
Executive dysfunction
Planning, juggling tasks, and switching between things feels harder. Executive function and psychomotor processing are among the most consistently affected domains.2
Symptoms that don't fade
Imaging research shows altered brain connectivity and persistent cognitive changes in patients up to 4 years after a TIA or minor stroke.7
Trouble at work
Many TIA survivors report difficulty returning to their previous level of work performance. The cognitive load that used to feel routine now drains the day.5

Why You Still Feel This Way
Standard care prevents the next stroke. It doesn't treat what the last one left behind.
The ER did its job. Imaging ruled out a bleed. You left with antiplatelet therapy, blood pressure medication, and instructions to follow up. None of that is designed to address brain fog, fatigue, attention, or mood.
What standard post-TIA care covers
- Acute imaging to rule out hemorrhage or large-vessel occlusion
- Antiplatelet or anticoagulant therapy to prevent the next event
- Blood pressure, cholesterol, and diabetes management
- Lifestyle counseling and risk factor screening
- Carotid imaging when indicated
What it usually does not cover
- Functional brain imaging that shows how regions are working together
- Domain-specific cognitive testing and rehabilitation
- Targeted therapy for processing speed, attention, and memory
- Treatment for post-event fatigue, anxiety, and mood changes
- A structured plan to return to work, school, or sport
International stroke rehabilitation reviews flag cognition after stroke and TIA as a top unmet need. Patients describe feeling "abandoned" once acute risk has been managed.11,12 That gap is exactly where Cognitive FX works.

Common Questions
What patients ask before scheduling
My MRI was "normal." Why am I still having symptoms?
Standard MRI shows structure. After a TIA, anatomy often looks intact while function is not. Functional MRI research has documented altered connectivity and disrupted neurovascular coupling years after a TIA, even when conventional scans are clean.7,13 A normal structural scan is good news for ruling out hemorrhage. It is not proof your brain is functioning normally.
How long after a TIA can treatment still help?
There is no hard cutoff. Patients have made meaningful gains months and years out from their event. Earlier is generally better, but the data on persistent post-TIA symptoms makes clear that "wait and see" is rarely the right answer when symptoms have already lasted weeks.
Is this the same program you run for concussion?
The core EPIC framework is the same: functional imaging, intensive multidisciplinary therapy, and a re-scan to verify change. The therapy targets are personalized to your fNCI findings, which look different in TIA patients than in concussion patients. The mechanism of injury differs, but the downstream pattern of disrupted networks, impaired neurovascular coupling, and cognitive symptoms responds to the same approach.
Will treatment lower my risk of another stroke?
Stroke prevention is your neurologist's domain: antiplatelet therapy, blood pressure control, lipid management, and addressing the underlying vascular cause. Continue all of that. Cognitive FX treats the residual symptoms and brain function changes that prevention medications do not address. We work alongside your medical team, not instead of it.
How long is the program and do I need to travel?
Treatment is a five-day intensive in Provo, Utah, roughly six hours per day. Most patients fly in. We help with logistics, and our patient care coordinators can walk you through hotel options, transportation, and what to expect.
What does it cost and is any of it covered?
Pricing details are on our pricing page. Insurance coverage varies. Many patients use HSA/FSA funds, and we provide superbills for out-of-network reimbursement when applicable. Our team will walk you through the specifics on your free consult call.
