Q. Is there any reason behind this? a bipolar woman is mostly misdiagnosed for depression…..is there any reason behind this?

A. freebrid12 is right, and there's another thing- depression is a very common diagnosis amongst women and bipolar is less common. therefore psychiatrist tend to diagnose depression more then bipolar disorder.

Q. I have been having chronic pain in sinus area and behind my eyes, been to ENT who states it is not infection? I wake up with the pain and go to sleep in severe pain. Its all day and all night. Dr insists that its migraine related and allergy related. I have chronic postnasal drainage. It started 4 months ago when I moved into our new house. The pain makes me extremely fatigue and dizzy at times. I have been referred to the eye doctor, a headache specialist and an allergy specialist. Just recently I have had a CT scan and an MRI, as well as xrays of my sinus. Nothing other than a deviated septum and possible allergies from an ENT has been diagnosed. In the mean time I am waiting for the days to come when I can get into see these specialist. Anyone out there have any of the same symptoms?? Need help here. Soooooo sick of the pain.

A. i have chronic sinusitis and can really relate to what you describe. learned to live with the pain...but still, i use various ways to reduce inflammation in my sinuses, i heat the place up before going to sleep, try to avoid eating or drinking cold stuff.
another thing i do is i heat water (80c) then add a special oil i bought in a chinese medicine store , about 5 drops, and inhale the fumes. nettle tea can do wonders too.

Q. info on arachnoid cyst in the right posterior fossa

A. Basically it's like a small sac filled with fluid. The problem is that the skull is a rigid closed space, which means that if there's something other than the brain, it'll occupy space, usually on expense of the brains' space. These kinds of problems are often referred to as "space occupying lesion".

It's usually congenital (i.e. develops during pregnancy), and even when it cause symptoms they develop slowly.

This measure of muscle tone provided an additional means of determining the depth of the bird's sedation, although the sedation score was the means through which onset and conclusion of sedation and dorsal recumbency were defined.
Dorsal recumbency was achieved in only 65% of birds that received the 5 mg/kg dose but in 95% of birds that received 10 mg/kg dose (P = .
Sedation was induced more rapidly (Fig lA), and both sedation and dorsal recumbency lasted longer (Fig lB) after administration of the 10 mg/kg dose than of the 5 mg/kg dose of diazepam (Table 1).
A 10 mg/kg dose of diazepam (triangles, right) was more effective than a 5 mg/kg dose (circles, left) in inducing sedation (filled symbols) and dorsal recumbency (open symbols) in adult zebra finches.
All the birds were sedated with a 10 mg/kg dose of diazepam, and all the birds achieved the dorsal recumbency state before subsequent testing (n = 20).
Potential IOP differences between right and left eyes and between upright position and dorsal recumbency were assessed by the Wilcoxon test for dependent variables.
The results may be caused by the study design, eg, the degree of dorsal recumbency.
