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

How are brain cancer and brain tumor different?

How are brain cancer and brain tumor different?

Pathology type: Brain tumor is a generic term that includes benign, low grade and malignant brain tumors. Brain cancer refers to the malignant category. When one speaks of a brain cancer, this may be a primary (originating from the brain tissue) or metastatic (originating from cancer outside of the brain). Treatment depends on the type of cancer. ...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

Can MRI of brain see strokes/mini strokes and tumours on pituitary gland?

Yes : If pituitary tumor is suspected a detailed endocrine evaluation is necessary to assess whether it is a functionally secreting tumor. Especially looking for acth secreting tumors given your history there are other types that present with generalized symptoms but a thorough endocrine evaluation should establish this in addition a very refined mri. ...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

I have a brain tumor also trigeminal neuralgia . I'm planning on the brain surgrey tumor on the trigeminal neuralgia nerve. Can they remove the tnnerv?

I have a brain tumor also trigeminal neuralgia . I'm planning on the brain surgrey tumor on the trigeminal neuralgia nerve. Can they remove the tnnerv?

Usually No: It sounds like you have a tumor (usually a meningioma or schwannoma) attached to the trigeminal nerve. This can cause the facial pain that you note. When surgery is done for this, the neurosurgeon can usually peel the tumor away from the nerve. Some fibers of the nerve can be sacrificed hopefully with minimal neurologic sequelae. This is a big nerve and it controls facial sensation and chewing. ...Read more

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

Can a MRI of spine detect aneurysm and nerve disorders?

Can a MRI of spine detect aneurysm and nerve disorders?

Possibly: Magnetic resonance imaging, is a non-invasive, non-radiation method of cross section imaging. It is used to look at soft tissues, blood vessels and bone. Mri spine imaging will look at bone and the spinal cord with spinal nerves cords. An aneurysm is a blood vessel defect, usually of an artery such as the aorta, which lies in front of the spine. Whether this is seen depends on the image window. ...Read more

How are cerebrum and cerebellum structures similar?

How are cerebrum and cerebellum structures similar?

Brain anatomy: Within the skull there is a thick membrane called the tentorium which partially separates the cavity into two main sections. The cerebellum is the brain tissue below the tentorium and the cerebrum is all the brain tissue above the tentorium The two are connected via the brainstem. ...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

Describe the features of a brain and spinal cord infection.?

Describe the features of a brain and spinal cord infection.?

Go to ER now: An infection of the area surrounding the brain can cause meningitis- fever, stiff neck, headache, and changes in conciousness. An infection within the brain itself is encephalitis- causing changes in personality, level of conciousness, and even seizures or other abnormal movements. These conditions are both very life-threatening, but treatable, and should be evaluated by a physician immediately. ...Read more

What specific Autoimmune diseases attack brain cells and neurons causing a dramatic effect to neurotransmitters,hormones and the function of the brain

Lupus: Systemic Lupus can attack everywhere and lead to the things u asked about. Other considerations are vasculitis syndromes as there is an autoimmune attack on and in blood vessels which can affect neurons indirectly. Myasthenia Gravis also affect the neuromuscular system and affects one of the main neurotransmitter, AcetylCholine. Rheumotologist is specialist to see for autoimmune disorders ...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
