Does the brain continue to deteriorate after a stroke?

What really happens to the brain after a stroke

A stroke is more than just a sudden, scary medical event — it’s like a wildfire in the brain. When blood flow is blocked (ischemic) or a vessel bursts (hemorrhagic), brain cells start dying. Fast. But here’s the catch: the damage doesn’t always stop when the stroke “ends.”

Yep, even after the person is stabilized, the brain may still be undergoing a silent, sneaky process of deterioration.

Delayed brain cell death: it’s a thing

What is secondary neuronal injury?

After the initial injury, the brain can enter a phase of secondary damage. This includes:

• Inflammation (microglia go wild)

• Oxidative stress (free radicals wreak havoc)

• Excitotoxicity (neurons basically overfire and self-destruct)

Sounds sci-fi, but it’s been well documented in stroke patients, especially in the days to weeks post-stroke. It’s a weird combo of the body trying to heal, but also causing more trouble while doing it.

And yes, that could mean additional brain tissue loss.

Wait, so can it get worse?

Sometimes, unfortunately, yes. If the stroke causes a big area of infarct (dead brain), surrounding tissue — what doctors call the “penumbra” — is at risk. Without proper intervention (think meds, rehab, even lifestyle changes), this zone can deteriorate too.

Cognitive decline post-stroke: more than just memory lapses

It’s not just about motor skills or speech. Some stroke survivors (especially older adults) face vascular cognitive impairment. That’s just a fancy way of saying your memory, attention, or problem-solving skills can slowly get worse over time.

Not everyone, of course. But it happens more often than people think.

My grandmother had a small stroke at 78. She bounced back quick — physically. But over the next two years, she started forgetting appointments, struggled with words, and eventually needed help with bills. Turns out, she had post-stroke dementia. It creeped in quietly.

Can you stop or slow down the brain's decline?

The power of rehab (and not just physio)

Early and aggressive rehabilitation — physical, occupational, and cognitive therapy — has been shown to preserve neural pathways and even spark neuroplasticity. That’s the brain’s amazing ability to rewire and adapt.

Also, there’s growing evidence that:

• A Mediterranean-style diet

• Regular aerobic exercise

• Social interaction

• Brain training apps (yeah, seriously)

can all help reduce long-term deterioration. It’s not a cure, but more like slowing the descent.

Medications and brain support

Depending on the cause and severity of the stroke, docs might prescribe:

• Anticoagulants or antiplatelets (like aspirin or clopidogrel)

• Statins (not just for cholesterol — they help the vessels too)

• Cognitive enhancers in some cases (e.g., memantine or donepezil)

But again, this isn’t a one-size-fits-all. The key is early diagnosis and a tailored plan.

Emotional and mental health: don’t underestimate this

A huge, often ignored factor? Depression. After a stroke, many patients feel down — really down. And that’s not just emotional; depression is linked to poorer recovery, more cognitive decline, and yes… possibly more brain deterioration.

Therapy, support groups, and yes, sometimes medication, can make a big difference.

So... does the brain keep breaking down after a stroke?

In short: it can, but it doesn’t have to. The risk is real — delayed cell death, cognitive changes, depression. But with the right support, treatment, and mindset, many people can stabilize or even improve.

Don’t brush off subtle signs after a stroke. Follow-up matters. And hey, the brain’s got this surprising ability to bounce back… if you give it a fighting chance.

Is 165 cm normal for a 15 year old?

The predicted height for a female, based on your parents heights, is 155 to 165cm. Most 15 year old girls are nearly done growing. I was too. It's a very normal height for a girl.

Is 160 cm too tall for a 12 year old?

How Tall Should a 12 Year Old Be? We can only speak to national average heights here in North America, whereby, a 12 year old girl would be between 137 cm to 162 cm tall (4-1/2 to 5-1/3 feet). A 12 year old boy should be between 137 cm to 160 cm tall (4-1/2 to 5-1/4 feet).

How tall is a average 15 year old?

Average Height to Weight for Teenage Boys - 13 to 20 Years

How to get taller at 18?

Staying physically active is even more essential from childhood to grow and improve overall health. But taking it up even in adulthood can help you add a few inches to your height. Strength-building exercises, yoga, jumping rope, and biking all can help to increase your flexibility and grow a few inches taller.

Is 5.7 a good height for a 15 year old boy?

Generally speaking, the average height for 15 year olds girls is 62.9 inches (or 159.7 cm). On the other hand, teen boys at the age of 15 have a much higher average height, which is 67.0 inches (or 170.1 cm).

Can you grow between 16 and 18?

Most girls stop growing taller by age 14 or 15. However, after their early teenage growth spurt, boys continue gaining height at a gradual pace until around 18. Note that some kids will stop growing earlier and others may keep growing a year or two more.

Can you grow 1 cm after 17?

Even with a healthy diet, most people's height won't increase after age 18 to 20. The graph below shows the rate of growth from birth to age 20. As you can see, the growth lines fall to zero between ages 18 and 20 ( 7 , 8 ). The reason why your height stops increasing is your bones, specifically your growth plates.
