Do all prion diseases predominately affect the brain or also the spinal cord and nerves?

Do all prion diseases predominately affect the brain or also the spinal cord and nerves?

Prion: Prions are proteins that have changed conformation, so that the normal function of the protein inside the cells won't work. The prions' also causes other normal proteins to misfold and make more prions, spreading the process. The prions affect many cells in the body, but they particularly harm nerve cells in the brain, causing progressive rapid degeneration. They are not alive, and have no dna. ...Read more

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

Involuntary tics in head are they from brain damage?

Involuntary tics in head are they from brain damage?

Not exactly: Tics can involve muscles in the head, face, arms, legs or any muscle group in the body. Facial tics are the most common. The cause of tics is unknown, but brain damage as from traumatic brain injury rarely cause tics. The cause is usually genetic, but there is evidence that tics may also arise as a consequence of certain infections such as strep. ...Read more

Could MS located in the spine cause symptoms primarily impairing brain function? Like lightheadedness (brain fog) and bad short term memory?

Could MS located in the spine cause symptoms primarily impairing brain function? Like lightheadedness (brain fog) and bad short term memory?

Not related to MS: MS in the spine wouldn't cause any issues with brain function. MS taking place in the brain could cause some issues with lightheadedness but not memory issues, it would have to be a very end-stage degenerative MS to cause such symptoms and even then it would likely be a secondary cause, not a primary. Other things such as vertigo, viral infections, stress, sleep etc could be benign causes of this ...Read more

Most neurons in the brain and spinal cord are not regenerated, right?

Most neurons in the brain and spinal cord are not regenerated, right?

Not quite correct: For years, it was felt that nerve cells would not heal. If the cell body dies (apoptosis), it does not resurrect. If the nerve fibre axon is transected, it will not reconnect. But the myelin covering can regenerate, and the brain can employ alternative pathway connections with time. ...Read more

Can electrical stimulation of diffrent areas of the brain stop mental disorders?

Can electrical stimulation of diffrent areas of the brain stop mental disorders?

"Stop" = remission: Brian stimulation therapies (bst's) rely on electricity, magnets, or implants applied to the brain to treat depressive disorders and other mental disorders. Electroconvulsive therapy (ECT) is the oldest and most researched of this treatment category. The consortium for research in ECT study, found an 86% remission rate for those with severe depression. There are 3 other promising bst approaches. ...Read more

Does c spinal cord injury affects brain function?

Does c spinal cord injury affects brain function?

No: Spinal cord injury affects portions of the body b elow the site of the injury. The brain is not affected, but these injuries are frequently very disturbing and sometimes dangerous. The person suffering from this can be depressed and needing of assistance in many other ways. ...Read more

What is the difference betweens cranial nerves and neurons in the brain. Is it possible to damage a major cranial nerve?

What is the difference betweens cranial nerves and neurons in the brain. Is it possible to damage a major cranial nerve?

Cranial nerves: Cranial nerves originate directly from the brain. Spinal nerves emerge from sections of the spinal cord. A nerve is made of a bundle of axons and surrounding myelin from many nerve cells (or neurons). The cranial nerves can certainly become diseased or damaged. For instance, pathology of cranial nerve vii, or the facial nerve, is known as bell's palsy. ...Read more

Could porn damage the brain and cause emotional numbness?

Could porn damage the brain and cause emotional numbness?

Why do you ask?: There a fair amount of refereed medical literature on the response to erotica, including levels of neurotransmitters, but nothing whatever to suggest that the brain itself is damaged. Almost all men look at images, and most lose interest soon as it's a dead-end -- the perfect bodies and fantasy situations aren't the real, true love that is what we know we really want. ...Read more

What happens when neurons die by injury!? Specific neurons in the brain , injury to the central nervous system.

What happens when neurons die by injury!? Specific neurons in the brain , injury to the central nervous system.

In most cases: neurons do not have the ability to regenerate, or have only a limited ability at best. There is significant redundancy and unused capacity with the brain's neural network, so depending on the location and extent of injury, it may be possible to compensate for some degree of neuronal loss due to injury. The damage itself is generally permanent, however. ...Read more

What areas of the brain will Parkinson's disease affect?

What areas of the brain will Parkinson's disease affect?

The substantia nigra: Parkinson's disease destroys the dopaminergic neurons that live in a part of the midbrain called the substantia nigra (dark substance). The loss of Dopamine causes the basal ganglia to malfunction and this causes the slowness, tremor and dementia. ...Read more

How do arteriovenous malformations damage the brain and spinal cord?

How do arteriovenous malformations damage the brain and spinal cord?

Hemorrhage: Most of the damage of an arteriovenous malformation occurs when the blood vessel or vessels are spontaneously ruptured and bleed into the brain, causing pressure and damage to the brain. The same can occur with an av malformation in the brain stem or spine. ...Read more

How are pinched nerves in back and sympathetic dystrophy distinguished using EMG/NCS?

How are pinched nerves in back and sympathetic dystrophy distinguished using EMG/NCS?

RSD: is a clinical diagnosis. The EMG-NCS tells you if there is muscle loss form nerve root injury or if there is other confounding situations like compression of a nerve (in the wrist, ankle hand, elbow, knee) or multiple nerve dysfunction or even diffuse neuropathy. One can also identify lumbar sacral and brachial plexus injury by identifying a pattern of muscle involvement downstream. ...Read more

In WHIPLASH INJURY the nerves originating from spine inside vertebral column, CAN NERVES SNAP OUT? Due to rapid movement of neck.

In WHIPLASH INJURY the nerves originating from spine inside vertebral column, CAN NERVES SNAP OUT?  Due to rapid movement of neck.

No: Short of a traumatic displaced fracture or dislocation of the spine, the nerves do not "snap out" of their normal position. They are protected by strong ligaments and the bone architecture of the vertebral column that would have to be disrupted for them to move into an abnormal position. ...Read more

What organ is most affected by stroke? The heart/circulatory or brain and spinal cord?

What organ is most affected by stroke? The heart/circulatory or brain and spinal cord?

Brain: Stroke is a condition that primarily affects the brain.There are ischemic strokes where a particular blood vessel is blocked and the part of the brain that is perfused is deprived of blood/oxygen and then dies.There are hemorrhagic strokes where there is the accumulation of blood in the brain (intracerebral hemorrhage)or aneuysmal bleed where the blood spills out into the outer layers of the brain. ...Read more
