Is the number of neurons remain constant throughout the life of an individual?

User Avatar

Asked by Wiki User

No. When you are born, you have the most neurons you will ever have. Until you are in your early 20's your brain continues to "trim" neurons from your brain, a mechanism that aids in learning and development. After this point, as you age, you begin to lose neurons, simply from age. After brain development is complete in utero, there are only two locations in the brain that are capable of generating new neurons: the hippocampus (thought to play a role in learning new information) and the olfactory bulb (learning and recognizing new smells).

How to avoid giving levodopa in high dose to Parkinson's patients?

User Avatar

Asked by Wiki User

Although levodopa can cross our BBB, but it will be decarboxylated to dopamine peripherally before reaching our CNS - only small amount of Levodopa will be left and available to pass our BBB.

So, instead of giving levodopa in high dose (which can cause lots of side effects), we give levodopa with peripheral decarboxylase inhibitors (e.g. carbidopa, benserazide) which can inhibit decarboxylation of levodopa in GIT and peripheral tissues. (By combining levodopa and peripheral decarobxylase inhibitors, we will have less side effects too)

What is levodopa?

User Avatar

Asked by Wiki User

To make it simple, Levodopa is the precursor of Dopamine and it's used to treat Parkinson's disease. (We don't directly use dopamine because dopamine can't cross our blood-brain-barrier, so, it won't be effective to be taken orally)

What neurotransmitter does a SNRI 'Serotonin Norepinephrine reuptake inhibitor' drug work on?

User Avatar

Asked by Wiki User

The S stands for serotonin and the N stands for norepinephrine and RI stands for reuptake inhibitor. So, obviously these drugs are supposed to work on both serotonin and norepinephrine. However, some literature uses SNRI to mean Selective Norepinephrine Reuptake Inhibitor, and this will work better on norepinephrine. Then you have the SSRI which is Selective Serotonin Reuptake Inhibitor, which works better on serotonin.

What are the contraindications of levodopa?

User Avatar

Asked by RedGuitar168

We don't give levodopa to:

  • psychiatric patients (because it will antagonize the effect of antipsychotics)
  • glaucoma patients (because it can increase our intraocular pressure)
  • peptic ulcer patients (because it might cause hemorrhage)

Tricyclic antidepressants compared to selective serotonin re-uptake inhibitors?

User Avatar

Asked by Wiki User

Tricyclics are more potent antidepressants compared to the newer SSRIs. The reason SSRIs tend to be prescribed more, however, is because tricyclics are less well tolerated due to their antimuscarinic effects, such as: dryness of mouth, constipation, dizziness, abnormal heart rhythm, blurred vision and urinary retention. Trycyclics cannot be given to people with with hypotension or heart problems. SSRIs generally have a longer half life (15-50 hrs vs. 12-32 hrs for trycyclics) and do not require as high a concentration in the blood as tricyclics for their therapeutic effect.

Why does starch react with iodine solution?

User Avatar

Asked by Wiki User

Iodine (a halogen) forms a starch-iodine complex by binding with amylose coils, which results in a transfer of charge between amylose and iodine, changing the energy levels of iodine atoms, and producing a dark blue color.
