What do you know about Lazarus Reflex? What do you know about Patients who are brain-dead? Of course, a lot of us have heard about it a lot of times, but do we know what it really is? In a brain-dead patient, is movement possible? Infact, do we think life is still certain? Let’s journey through the story of Teniola to see our questions get answered.
She didn’t only Jerk her fingers, She also moved her toes – Lazarus Reflex
“Madam, your daughter still shows no signs of brain activity.” The doctor told Mrs. Afolabi.
“But I saw her move her hands.” Mrs Afolabi stated.
“She’s brain dead. The electroencephalogram(EEG) tests did not show any brain activity. There is irreversible loss of brain function”. He explained.
Mrs. Afolabi, not believing the doctor, argued.
“Are you calling me a liar? That I do not know what I’m saying? Teniola, my daughter did not only jerk her fingers, she also moved her toes. In fact, she raised her arms to her neck and dropped them crossed on her chest. I’m sure she’d have opened her eyes to call mummy if not because of my village people. They’ll surely be shamed.”
Mrs. Afolabi, crying, further added, “What other evidence do you need to tell you my daughter is still alive? Haaaaa, you need to repair your machine.”
“Calm down madam.” The doctor gently said.
“I’m not calming down oo. When Sade’s mum was told that her daughter was in a coma, Sade was brought back to life. My Teniola’s own won’t be different.” She kept on emphasizing.
Being Brain-dead is Different from being in a Coma
“Madam, being brain-dead is different from being in a coma. Brain death refers to the death of brain tissue and once the tissue dies, nothing can be done to heal it, I’m sorry madam.” He explained.
“Something must be done oo doctor, she’s my only child. The only person I have in this world.” She said between tears.
The doctor, still explaining added, “Anyways madam, what you observed is so very likely, but it doesn’t mean your child is back to life. We refer to such movement as Lazarus reflex or Lazarus sign.”
Lazarus reflex is different from Lazarus Syndrome
With a newly found faith, Mrs Afolabi stated confidently, “OMG! Lazarus sign really? Don’t worry, my Teniola will come back to life like Lazarus did in the Bible…”
What is Lazarus Reflex?
Lazarus sign or reflex is a reflex movement that happens in brain-dead patients. It causes them to briefly raise their arms and drop them crossed on their chests. It is normally mediated by a neural pathway which passes through the spinal column but not through the brain. Again, the movement is possible in brain-dead patients whose organs have been kept functioning by life support machines.
As earlier stated, it is imperative to understand that the movements are spinal reflexes that do not involve brain activity. This is because the cells ordering such movements are located in the spinal cord and not the brain. Therefore, when a person is brain dead, the body’s entire system stops. One cannot breathe, the heart cannot beat and the body cannot function on it’s own once the brain dies. However, occasionally reflexes such as arm movements might occur.
Has anyone survived brain death?
With all certainty, medically, life is impossible after brain death. Experts have made it known that a brain-dead person is as good as dead. Therefore, if ever they say someone recovers from it, I’ll assume it was a misdiagnosis in the first place. I can as well call it a medical miracle, but who can say?
For Teniola and in every other patients with such case, recovery was impossible after brain death. Therefore it wasn’t logical to continue life sustaining treatments.
However, the treatments were significant to Teniola’s mother. The ventilator, hormones and fluids, made her daughter’s body carry out some biological processes, but they were just temporary.
What happened to Teniola?
Teniola, her mother’s daughter, eventually died fifteen days later.

But what causes brain death
Cardiac arrest, severe head injury(from gunshot or a fall or a vehicle accident), brain tumor, infection, heart attack, stroke e.t.c
It can be hard to diagnose though, as it can be confused with being in a coma, which is different from that.
Brain death is death!
Nice write up👍👍👍
It was stated in the story that ” It is normally mediated by a neural pathway which passes through the spinal column but not through the brain”.
And my question is; can spinal column works on it’s own without brain?
I think brain is the genesis of neurons, how can spinal column works without brain functioning?
The CNS is made up of the brain and spinal cord. They both have their functions, and they work together. Also, like you said, they are made up of neurons, which are the motor and sensory neurons. The motor neurons act on muscles, while the sensory, convert external stimuli into internal ones.
The neural pathway now, which normally involves the brain and spinal cord, controls a reflex action.
But the thing is, most reflexes do not pass through the brain but spinal cord, especially in higher animals.
This is because the spinal motor neurons get activated first without the delay in routing signals first through the brain.
A reflex action doesn’t require a thought input first. This should explain why we jerk our hands immediately off a hot object… without thinking.
It should be noted however that the brain can eventually receive impulses while the reflex action occurs.
Thanks for the answer.
Hann is stuffy, aside doing well putting the piece together, your neuroanatomy is sturdy
Wow a nice write up. But how about 15days as in Tenionala’s case, does it take longer time than normal death
It depends. If a brain-dead patient is supported by ventilator and other stuffs, he/she isn’t declared dead yet, since the body has been made to carry out some biological processes. In that situation, when it gets to a point where the body can’t be supported anymore, death happens, just like in Teniola’s case.
You’re doing well 👍
