What are the symptoms of Brain Cancer


Brain tumours can present with generalized headaches which are usually worse early in the morning. Over time, they tend to wake people up earlier and earlier. The reason for this is increased intracranial pressure. There is only so much space inside the skull so anything extra will c... Read More

What are the differences between hypoxia and hypoxemia


Hypoxia and hypoxemia are two entirely different terms often used interchangebly.Hypoxia - It is either the inability of the body tissue or organ to utilize oxygen or decreased oxygen supply to the body tissues and organs.Hypoxemia - It refers to decreased level of Oxygen in the arterial blood.L...

Are high levels of dopamine associated with higher intelligence


I took two pharmacology classes in college. I know about neurotransmitters. I’m aware of dopamine. Dopamine has five receptors in the brain. They are divided into two families. D1 and D5 are the first one. D2, D3, D4 are the second one. D1 and D5 are both activating Adenylate cyclase which promo... Read More

Does depression cause brain damage


Actually, that's a pretty interesting concept. The brain is a very_very_complex organ, and there's so much we don't know or understand about it, however based off images of the brain taken through a PET (Positron Emission Tomography) scan it shows that a depressed brain is in a way “damaged”. Th... Read More

What are some neuroscience hacks to become smarter and genius


There are no neuroscience hacks to achieve your goals. IQ is determined genetically and can be lowered by environmental factors, such as head trauma, disease, and exposure to toxins. Efforts have been made for many years to find a means of increasing intelligence. No practical means has yet been... Read More

Why can't brain cells reproduce


A typical mature neuron has a network of hundreds if not thousands of branches connecting it to other neurons, and these connections are what determine brain function.These connections are also built up slowly over years and decades of experience and reinforcement signalling.In order to divide...

Can stem cells cure or reverse neuropathy


Neuropathy sufferers now have a new, minimally invasive therapy option: stem cell treatment for neuropathy. Stem cell therapy for neuropathy is an alternative, revolutionary approach to relieving your neuropathy pain and symptoms. A stem cell's primary function is to repair and regenerate damag...

Neuroscience: Yes, Brain Training Actually Can Work When Done Correctly


For best results together with your own brain training you'll specialise in a couple of main points:Awareness:Once you are often increasingly conscious of your own experiences, reactions, and limitation, you'll be ready to guide your own brain training regimen. Listening to the days you grind to... Read More

What is the difference between non receptor tyrosine kinase and receptor tyrosine kinase


After binding of the ligand, the receptor tyrosine kinase (RTK) autophosphorylates Tyrosine -> activates GRB2 -> SOS -> RAS -> downstream kinase -> transcription factors. Think anabolic/growth factors - Insulin, IGF-1, FGF, PDGF, and EGFNonreceptor tyrosine kinase recepto... Read More

What are the differences in the following: dementia, Lewy Body dementia, and Alzheimer's


Dementia is a category of disease, not a diagnosis. It indicates that there are problems with cognition severe enough to interfere with daily function.AD is the most common form of dementia. It is characterized by plaques (beta amyloid) that form outside the neuron, and tangles (tau tangles) tha... Read More

What are the signs of ADHD


Well, I must admit that Diagnosing ADHD isn’t just about reading symptoms and reading relate able posts. It’s much beyond that. It requires a psychologist and various tests and behavioural observation over a period of time. It could often have overlapping symptoms with Bipolar Dis... Read More

What are white matter and gray matter


Gray matter is the part of brain where cell bodies of nerve cells reside. Normally the gray matter forms the outer part of the brain and certain islands of tissues deep within the brain like basal ganglia nuclei, thalamic nuclei etc. The axons of the cells present within these areas travelling d...

What are brain abscesses


An abscess is a pocket of necrotic, degenerating tissue, often with infection, in any organ ranging from skin and gums to liver and kidneys. A brain abscess is a life-threatening condition requiring emergency intervention. It begins as inflammation and, without intervention, progresses to an abs... Read More

What is the difference between toxic and neurotoxic venom


Neurotoxicity occurs when exposure to natural or artificial toxic substances, which are called neurotoxins, alters the normal activity of the nervous system in such a way as to cause damage to nervous tissue. This can eventually disrupt or even kill neurons, key cells that transmit and process s... Read More

Do we have a limited amount of neurons? Do they regenerate or does our brain make more


There are a lot of archaic and inappropriate answers here, please disregard them. The only the one that is correct by current scientific understanding as of 2019, provided by Xeno Rasmusson, is nice enough to point out that the idea of what’s valid about this topic is something that ch...

Why do old people generally suffer from brain disorder


All old people suffer from brain atrophy.Some old people suffer dementia.The brain cells (neurones) you were born with are all the brains you’re going to get, and every day 1,000,000 of those precious cells die. Yet you can lose half your brain and still retain personality and memory.Every time... Read More

What are the main major symptoms of brain tumours


Brain resides inside a precisely pressure-controlled cavity covered by a hard skull that does not allow brain or anything inside to expand in size.When a tumour mass grows from inside this hard skull (be it from brain or from its coverings), it tries to occupy more space at the cost of space mea...

What is the difference between psychiatry and Neuropsychiatry


Psychiatry is a broader field. Although it is a subspecialty of medicine, it can be considered a speciality in itself, as medical students don't have adequate exposure to psych in their MBBS days. It deals with the thoughts, mood and behavioural symptoms affecting the mind.Neuropsychiatry is a su... Read More

What are some ways to treat early signs of Parkinson's disease


While making an early diagnosis of Parkinson’s can be difficult, one can always look out for warning signs. The early signs that are detected are the loss of smell, depression and anxiety, sleeping disorder, etc. Starting with the sleeping disorder, it can be caused due to physiological changes i...

Is there a way for a pwBPD to prevent memory loss


I may be way off here, but memory loss would not be my first take on what people with BPD are inclined to experience without considering two things. These would be the co-occurrence of depression and dissociative symptoms (ruling out cognitive decline due to aging, drug use, brain damage, and oth... Read More

What are non-medical treatments for Parkinson's disease


"Treatments" can be divided into two categories. 1) Neuroprotective treatments slow, halt, or reverse the underlying neurodegenerative process that causes the loss of cells in the brain. 2) Symptomatic treatments improve the symptoms of Parkinson's disease without slowing the underlying course....

How effective is Noopept


Noopept is one of the strongest nootropics available on the market today. It provides a boost to overall cognition and has a slight psychostimulatory effect. Contrary to most nootropics, Noopept's effects start within mere minutes of ingestion making it an excellent choice right before mentally... Read More

Is there an association between brain size and Neurodegeneration


There are more variables than brain size involved.If you had a brain MRI performed, and the doctor who interpreted the results rendered your smaller brain like a death sentence, then we have a shared experience. I fled to a specialist - a neuropsychologist - and he stated the same finding was “... Read More
