r/BrainFog

I started suffering from chronic brain fog around 2025. I basically couldn’t think and could barely function. Being a science student that affected me a lot considering I had to maintain academic standards to get into med school.

Last year was absolute hell for me. Had to withdraw from my second semester of university because of this. It felt like my brain was just numb all the time.

By the start of 2026, I had tried everything and went to every doctor possible, but no medication was giving me any relief.

I then started sitting in sunlight. Not just any sunlight but the sunlight in the first hour after sunrise and the last hour before sunset. So i would sit for 20 minutes in the sunlight in the morning and 20 minutes in the evening.

I’ve been doing this for a while now and I have never felt better. Brain fog is basically non existent and my sleep has also improved significantly.

Honestly, nothing better than what nature has already given you.

Give it a try.

I spend around 7.5-8 hours on smartphone. Maybe this could be the reason behind my brain is not working properly.

Problems I face -

1. Trouble following someone's instructions

2. Forget the tasks I am supposed to do

3. Sometimes forget items I am supposed to buy

4. Lacking presence of mind often

5. Making silly mistakes while doing some task after fair amount of time

6. There are some things which I used to remember in past but no longer can recall it.

7. I feel mentally overwhelmed whenever I try to learn some hard thing.

I don't smoke or drink. People often complain about my brain fade or dumbness.

I’ve been 4 years brain fog free.

Before that I suffered from brain fog during 3 years. I entered remission by: starting a medication for an underlying autoimmune condition, starting magnesium supplements, and exercising.

However, 6 weeks ago I started having episodes again, almost daily. One of the few changes I had made was using a sweetened version of a protein supplement, and it turns out I confirmed that when I consume sucralose-sweetened products my brain fog comes back really quickly. Don’t know why.

Has this happened to anyone else here?

Can you tell what type of meds or any other thing that i should do to get it cured???

I’m 28F and had severe brain fog from age 18 to 28 that progressively worsened. I tried everything: clean eating, cold showers, social media detoxes, brain games, fish oil, memory pills, fixing iron and vitamin D, drinking 2L of water daily, speech lessons, strict sleep schedules (7.5 hours nightly for years), and intermittent fasting. Nothing helped.

The brain fog affected my memory, speech, and processing. I couldn’t keep a job longer than 10 months because I struggled to follow conversations and forgot things easily managers had to email instructions since I couldn’t process verbal ones. It also damaged my friendships: I’d forget important things friends told me, lose words mid-sentence, mispronounce common English words (despite it being my native language), and came across as “dumb.”

Three months ago, during a routine checkup, my doctor noted my resting heart rate on the higher end of normal range and suggested daily brisk walking. I’d been mostly sedentary and never did much moving around besides house chores and the rare hike. I started with 10 minutes and worked up to 30 minutes daily. At the same time, I also started building small wellness routines instead of trying to “fix” myself overnight. I used tools like journaling, breathing exercises, light mental activities, and mixing physical + brain activities together through apps like Soothfy, which helped me stay consistent without feeling overwhelmed. Since then, my brain fog has completely disappeared and I mean completely. I breathe deeply instead of shallowly, think clearly, remember conversations, and have laser-sharp focus it feels like my brain is finally getting enough oxygen after being starved for many years. I only noticed improvements after consistently brisk walking for 1 month and ensured I was always nasal breathing while walking. Please try brisk walking 30 minutes for at least a month it will be a game changer!!!

I need a supplement, nootropic, or medication to cut through the crippling brain fog I experience as a consequence of an undiagnosed sleep disorder.

The Sleep Issue:

• First 4–5 hours: Good quality sleep.
• The rest: I wake up, fall back to sleep easily, but experience a series of microarousals until reaching 7–8 hours total.
• The Morning After: I wake up feeling like dogshit. Body fatigue, severe brain fog, puffy face/eyes, irritability, and occasional mild nausea. It’s horrible—the brain fog feels like a demon subverting my brain.

The point is, while I am actively trying to diagnose and treat the root disorder, I desperately need to manage the daytime symptoms.

What specific compound or protocol do you recommend to noticeably reduce fatigue and brain fog so my life isn't on a complete, degraded pause?

I’ve heard of Modafinil and Mitogo (Biogent), but I’m open to any suggestions that actually move the needle. What works for you guys?

I recently found out by chance that I have a 1.9 mm saccular aneurysm. My doctor said it’s not an emergency, but he recommended a flow diverter stent procedure. I’m 29 years old and honestly very scared of the possible risks and complications.

Do you think waiting around 3 months would be risky? I really want to have a nice summer before going through the procedure. Since I discovered this incidentally, it still feels unreal to me.

Hey everyone, I need some advice or just someone to tell me I'm not going crazy.

Lately, I’ve been experiencing some serious memory and focus issues, and it’s honestly starting to scare me. For context, I am a university student diving really deep into a highly technical field (cybersecurity, networking, and complex tech concepts). It requires a massive amount of brainstorming, deep focus, and mental effort on a daily basis.

I am 20 years old, dealing with high stress levels, and although I get a good amount of sleep (7 to 9 hours) starting late around 2 AM, the actual quality of my sleep is really poor, I work out on and off, and I don't consume any drugs or alcohol at all.

But recently, my brain just feels... broken. Here is what's happening:

• Losing my vocabulary: I keep forgetting basic words in my native language. I know exactly what I want to express, but the words just get stuck on the tip of my tongue.
• Forgetting names: I forget the names of people I know if I haven't seen them in just a short while, my mind goes completely blank when we meet, even though they remember my name perfectly.
• Zero passive retention: I'll watch a movie, and shortly after, I can't even remember the core plot or specific scenes I watched.

It feels like my brain’s RAM is completely full and it's just deleting random, everyday files to keep functioning for my studies.

Has anyone else experienced this kind of extreme brain fog or memory loss purely from academic burnout, mental overload, or intense studying? If you have, is this normal? And more importantly, what did you do to snap out of it and get your cognitive sharpness back?

Any advice, routines, or habits that helped you "reset" your brain would be hugely appreciated!

just leaving this here in case it helps anyone. it turns out i was gluten intolerant, but without any sort of digestive symptoms. i noticed that water fasting for 2 days helped a little bit with the brain fog and my memory issues, and decided to try the carnivore diet to figure out whats up, and it changed my life. no more forgetting what i was about to say/do, no more weird random anxiety throughout the day, no more being tired in the morning regardless of how much i sleep, etc. its for the first time in my life that i can sit in a lecture and my brain can grasp whats being said.

diet is definitely something worth looking into before you suspect its a deeper problem :) good luck!

Title: 6-7 years of brain fog resolved — fish oil, protein, and lessons from an AA/EPA ratio of 53 (creatine helped then failed me)

I want to share what finally worked for me after 6-7 years of brain fog, because I wish someone had posted this when I was searching for answers.

**My symptoms**

Brain fog for years, dry skin, dry eyes, weak digestion, morning fatigue, anxiety, racing thoughts, post-meal sleepiness, poor sleep, and left neck and shoulder stiffness. Standard blood tests kept coming back normal so doctors had no answers.

**What I tried first — creatine (promising start, then failed)**

Creatine felt like a miracle at first. Brain fog cleared, sleep was genuinely great — I was waking up feeling the way you feel after a really good afternoon nap, that refreshed, fully rested feeling. I thought I had found the answer.

But with prolonged use things started going wrong. I started feeling tired and drained in the evenings. And every time I stopped taking it, the brain fog came straight back — sometimes worse than before, sometimes not as bad. It became clear creatine was providing temporary energy to a system that was fundamentally broken, not actually fixing anything. I moved on.

Note for others: if creatine worked brilliantly for you at first but then stopped — that's actually a signal worth paying attention to. It likely means your underlying issue is inflammation or metabolic, not just an energy deficit.

**The turning point — fish oil at high dose**

I got my AA/EPA ratio tested and it came back at 53. For context, optimal is below 3 (Japan average) and anything above 20 is considered high inflammation. At 53 I was in very high systemic inflammation territory — and this single number explained every symptom I had.

I started fish oil at 1800mg EPA/DHA daily. The effects were almost immediate. Within days brain fog started lifting. Skin and eye dryness resolved. Anxiety reduced. Digestion improved. I felt more present, less irritated, able to think clearly and more focused. Sleep took 1-2 months to fully normalize but it improved steadily.

Note: I initially had some trouble sleeping when I started high dose fish oil — this settled within a few weeks as my body adjusted.

**What the high AA/EPA ratio was actually doing**

Arachidonic acid (AA) embeds in cell membranes and makes them stiff and rigid. When your cell membranes are stiff, insulin receptors stop working properly — causing insulin resistance. This leads to blood sugar instability, energy crashes, post-meal sleepiness, and poor sleep. It also causes neuroinflammation which is brain fog. One root cause cascading into everything.

For Indians specifically this is very common — high sunflower and refined oil consumption combined with a genetic tendency to convert omega-6 to AA more aggressively creates the perfect storm.

**Adding protein — resolved post-meal sleepiness completely**

Even after fish oil I still felt sleepy after meals. Adding a protein shake in the morning and prioritizing protein at breakfast resolved this almost completely. Post-meal sleepiness is a classic early sign of insulin resistance — protein slows glucose absorption and prevents the blood sugar spike that causes it.

**Where I am now**

Brain fog — gone. Dry skin and eyes — resolved. Anxiety — significantly reduced. Post-meal sleepiness — gone. Digestion — improved. Energy — stable throughout the day. The one remaining issue is early waking around 3-4 AM which I am still working on and improving.

**Key tests worth getting if you have brain fog**

AA/EPA ratio (most revealing test I did), fasting insulin, HOMA-IR, triglyceride to HDL ratio, vitamin D, vitamin B12, and hs-CRP. Standard panels will likely come back normal — these specific markers tell the real story.

**What I wish I knew earlier**

Brain fog is often inflammation. Inflammation often comes from the omega-6 to omega-3 imbalance. Cooking oil is the biggest driver of this that nobody talks about. Fix the oil, fix the membrane, fix the receptor, fix the brain. It took 6-7 years to find this — hope this saves someone else that time.

Happy to answer questions about the protocol, dosing, or testing.

I have used claude to frame this as I have been interacting with claude from the time creatine worked for me, wanted to create my overall experience post which claude is aware of as I have been interacting with it.

I’m writing this because I honestly feel desperate and isolated, and I want to know if anyone has experienced something similar.
Around the COVID pandemic in 2021, I suddenly developed severe stuttering and extreme brain fog. Before that, I had NEVER stuttered in my childhood or earlier life. It came out of nowhere.
In 2022, after starting an SSRI, the stuttering and brain fog disappeared almost completely for about a year.
Then in early 2024, everything suddenly came back again for no obvious reason. The stuttering and brain fog became so severe that I had to stop private tutoring, which I previously loved doing. Around the same time, I also developed severe anhedonia for about 6 months — I completely lost my libido, couldn’t feel pleasure, motivation, or emotional connection to anything.
Then in summer 2024, when my Effexor (venlafaxine) dose was reduced from 150 mg to 75 mg, something strange happened: the stuttering, brain fog, and anhedonia almost completely disappeared for about 2 months.
In 2025, we also tried switching from Effexor to Trintellix (vortioxetine), and during the first few days of the switch, the stuttering and brain fog suddenly improved again for a short time — then the symptoms returned.
Since winter 2024, the stuttering, brain fog, and anhedonia have continued to come and go, but overall they remain severe.
My psychiatrist and I have tried many different medications and dose changes, but nothing has really helped long term.
At this point I feel extremely hopeless. I barely have any motivation left to live.
Because of the brain fog and stuttering, I’ve become isolated from my family and friends. I can barely communicate normally anymore or feel connected to people. It feels like I lost the person I used to be.
If anyone has experienced something similar — especially sudden adult-onset stuttering + brain fog after COVID — please share your experience. And if you managed to recover or improve, please tell me what helped.
TL;DR: Sudden onset stuttering and severe brain fog after the COVID era, temporary improvement with SSRIs, Effexor dose reduction, and briefly during switching to Trintellix — then relapse. Looking for people with similar experiences or recovery stories.

Background:

It started 2 years back when I was in final year of uni. Initially I ignored it considering lack of sleep, fatigue, caffeine intake etc.

However, it got worse with time.

Later I visited a neurologist but all regular blood tests, B12, iron levels etc were normal. Even MRI scans were normal.

Everything was attributed to stress, anxiety etc but I knew that was not it

Symptoms:

The pattern was inconsistent. Sometimes lasting a few hours to the entire day. Sometimes since waking up, sometimes the entire day went by but nothing happened. Finally I found a pattern- the trigger after a shower was most consistent.

Final diagnosis:

I underwent a sleep deprived EEG. It showed generalized epileptiform discharge. That was it.

I was put on anti seizure medication.

Now I can feel the cognitive difference.

So don't give up. It's tough but I hope my story helps someone.

no PMO will help me to cure if i have a brain fog , how many days should i wait ?

Was talking to someone in person that told me that they had brain fog and that taking Adderall help relieve their brain fog. I noticed that I have more mental stamina when using high amounts of caffeine which helps delay brain fog. Has anyone has success with stimulants such as adderall, Ritalin, or amphetamine?

How to study with brainfog. Can you suggest some techniques to retain information quickly because in the next month I have a exam. It is possible to crack tough competitive exam with brainfog.

I hope I'm not jumping the gun, but it feels like I may have solved my recent (last few months) bout of brainfog-like symptoms. This time it was triggered by instant noodles/ramen. I stopped eating that a week ago and have felt a gradual improvement, last night and today felt remarkably better.

It seems I'm quite sensitive to diet and supplements, due in part to my job which involves high volumes of high complexity tasks and frequent context switching. Small changes in my focus, cognitive state and mood get amplified.

One previous trigger was coffee, but I was very stressed at the time; I have been drinking coffee again recently without negative effects. Another was a supplement I used - Himalaya Mentat. Interestingly, at first it solved the problem with coffee, but after a while became the cause of the problem.

Just sharing in case it helps someone else. Ymmv.
