What is the function of Benserazide when combined with L-DOPA?

- Levodopa is a precursor to the neurotransmitter dopamine which is administered to increase its levels in the central nervous system. However, most levodopa is decarboxylated to dopamin before it reaches the brain, and since dopamin is unable to cross blood-brain barrier, this translates to little therapeutic gain with strong peripheral side effects. - Benserazide inhibits the mentioned decarboxylation, and since it itself cannot cross the blood-brain barrier, this allows dopamin to build ip solely in the brain instead. Adverse effects caused by peripheral dopamin, such as vasoconstricion, nausea, and arrythmia, are minimized.

What is lissauers tract?

= Posterolateral tract is a small strand situated in relation to the tip of the posterior column close to the entrance of the posterior nerve roots. It is present throughout the spinal cord, and is most developed in the upper cervical regions. The neurons and axons that make up Lissauer's tract are involved mainly in transmitting information from pain- and temperature-sensitive afferents to the neighboring segments of the spinal cord. Collaterals of unmyelinated and thinly myelinated axons of small primary sensory neurons (C and A-delta fibers, respectively) both ascend and descend for at least a few cord segments in Lissauer's tract

Myasthenias as a group of diseases

? Autoimmune maybe? Acetylcholine release/receptor function? (Myasthenic syndromes: Myasthenia Gravis, Lambert-Eaton myasthenic syndrome)??

Vascular dementia

? In vascular dementia, changes in thinking skills sometimes occur suddenly following strokes that block major brain blood vessels. Thinking problems also may begin as mild changes that worsen gradually as a result of multiple minor strokes or other conditions that affect smaller blood vessels, leading to cumulative damage. Vascular brain changes often coexist with changes linked to other types of dementia, including Alzheimer's disease and dementia with Lewy bodies. Vascular dementia is widely considered the second most common cause of dementia after Alzheimer's disease, accounting for 20 to 30 percent of cases. No approved drugs for this. Some alzheimer´s drugs are in trial.

Lesion of posterior part of parietal lobe can cause?

Agnosia - inability to process sensory information Dysgrafia Dyscalkulia (Gerstmann syndrome) (wiki - apraxia and hempispatial neglect) RW: Fundamentals of Neuro: Parietal lobe syndrome manifests itself in somatosensory deficits and a variety of neuropsychological abnormalities: The most prominent sign is usually a* hemisensory deficit.* Lesions of the language-dominant hemisphere (usually left) can cause left/right confusion, *finger agnosia, acalculia, and agraphia (These 4 = Gerstmann syndrome), and/or astereognosia.* Lesions of the nondominant hemisphere (usually right) can cause anosognosia (see above). With regard to motor function, there are often poorly coordinated, ataxic hand and foot movements on the side opposite the lesion. With regard to somatic sensation, there may be neglect for the contralateral half of the body (so-called extinction phenomenon: raw sensation is intact blaterally, but if the examiner touches the patient simultaneously and equally intensely at mirror-image sites on the two sides, the patient will report having felt something on one side only). Deep-seated lesions may produce contralateral ho- monymous lower quadrantanopsia or hemianopsia, or else only visual neglect for the contralateral hemifield.

What is parietal syndrome?

Problems in spatial orientation are produced by *damage to the parietal lobe*, typically in the right hemisphere. Spatial abilities are used when one forms a "mental map" of an area, or when one figures out how shapes will fit together. For example, in the acute phase (soon after injury) they get lost easily. What about neglect if it is in non-dominant hemisphere? Teuber test http://www.intropsych.com/ch02_human_nervous_system/parietal_syndrome.html

Reaction against aquaporins 4. *Neuromyelitis optica*, is an autoimmune, inflammatory disorder in which a person's own immune system attacks the optic nerves and spinal cord.

Although inflammation may also affect the brain, the lesions are different from those observed in the related condition, multiple sclerosis. Spinal cord lesions lead to varying degrees of weakness or paralysis in the legs or arms, loss of sensation (including blindness), and/or bladder and bowel dysfunction. RW: simultaneous appearance of symptomatic foci in the optic nerve and spinal cord; mainly affects young women; elevated CSF protein; no oligoclonal bands in CSF; inflammatory axonal damage

Lesion between pontine center for urination and sacral center for urination will affect the bladder in which way?

Spinal cord injury above the lumbosacral level eliminates voluntary and supraspinal control of voiding, leading initially to an *areflexic bladde*r and complete *urinary retention*, followed by a slow development of *automatic micturition* and neurogenic detrusor overactivity (NDO) that is mediated by spinal reflex pathways. However, voiding is commonly inefficient owing to simultaneous contractions of the bladder and the urethral sphincter (detrusor-sphincter dyssynergia) The sacral micturition center is located at the S2-S4 levels and is responsible for bladder contraction. The pontine micturition center acts as a central relay and may play a role in the coordination of external sphincter relaxation with bladder contraction. The cerebral cortex plays an inhibitory role in relation to the sacral micturition center.

Thomayer test - bad enligsh -->

Thomayerova distance Thomayerova distance, which is sometimes referred to as a simple crouch test. Display and evaluate non-specific mobility throughout the spine. It consists bent conducted from a standing position, when in extreme position, measure the distance of the third finger from the pad. Under normal result is considered touch of your fingertips, yet we tolerate distance of 10 cm, 30 cm above, it is the clear pathology. During the test we have to be careful about certain distortion - movement can be compensated by moving the hips or vice versa is restricted due to shortening of the knee flexors (patient shrugs her knees and feel pain in the knees). Except hypomobility test can investigate and significant hypermobility, when the patient touches the floor the entire hand or forearm (it is considered a very important disorder of connective tissue). Increased ligament laxity and thus the positive examination hypermobility is more frequent in women.

Hypoventilation occurs if a patient has increased intracranial pressure?

yes RW: Disagree"Hyperventilation is one known method of rapidly lowering ICP. Cerebral blood flow is largely dependent on PaCO2. Hyperventilation causes decreased PaCO2 which subsequently leads to arterial vasoconstriction thus lowering cerebral blood flow (CBF), cerebral blood volume, and ICP. This effect is mediated my pH changes in the extracellular fluid which cause cerebral vasoconstriction or vasodilation depending on the pH. There is approximately a 2% decrease in CBF for every 1 mmHg decrease in PaCO2 levels: - but if they are compressing the breathing centers - that is a different story. RR: I agree with the hyperventilation part -- but for treatment. So It should be correct if the breathing centres are being compressed...
