neuromd2012 :

Welcome to Just Answer. I am an Adult Neurologist and was contacted to answer your question.

neuromd2012 :

Hello. he did a Hoffman's sign test

neuromd2012 :

that is a test to check your cervical spinal cord and brain

neuromd2012 :

to see if there is a problem of the motor pathways in that area

neuromd2012 :

hello

Customer:

what is normal?

neuromd2012 :

well normal is a non-exaggerated response

neuromd2012 :

so your middle finger does not jerk excessively

neuromd2012 :

it is comparitive left and right

neuromd2012 :

comparative

Customer:

the left did feel "dead"

neuromd2012 :

he was checking you for demyelinating diseases like subacute combined degeneration

neuromd2012 :

which is vit B12 deficiency

neuromd2012 :

or MS, or any disease like lupus vasculitis, etc, that can effect the brain and spinal cord

neuromd2012 :

I see

neuromd2012 :

well it can be dead in a peripheral nerve problem,

neuromd2012 :

like a neuropathy, or pinched nerve in your neck

neuromd2012 :

on that left side

Customer:

my whole left side feels asleep, from face to top of foot

neuromd2012 :

did you get an MRI of your brain? do you have hypertension, diabetes

neuromd2012 :

any medical disorders?

Customer:

im waiting for insurance to ok the mri w/contrast. and I have dm2.

neuromd2012 :

well

neuromd2012 :

if you have DM2

neuromd2012 :

you can have a thalamic stroke, a lacunar stroke

neuromd2012 :

and have one sided numbnesss, face, arm and leg

neuromd2012 :

the MRI will show it

neuromd2012 :

that would be the most likely cause

Customer:

what is thalamic and lacunar?

neuromd2012 :

the thalamus is an area deep in the brain

neuromd2012 :

it is a white matter area

neuromd2012 :

and it has very small blood vessels which supply it

neuromd2012 :

when you have diabetes, you can close up those small blood vessels

neuromd2012 :

and cause a "lacunar" stroke, which is a small area in the thalamus that has lost blood supply

neuromd2012 :

it is in the "pathways" of sensation, so it disrupts your sensation to the entire side of your body

neuromd2012 :

is it called a pure sensory stroke

neuromd2012 :

it is part of having "microvascular' disease of the brain

Customer:

ok,can it be seen with an mri? is there treatment or reocurrance issues?

neuromd2012 :

yes

neuromd2012 :

it is seen on the MRI

neuromd2012 :

treatment is better control of your diabetes, and taking a medication to thin your blood

neuromd2012 :

either aspirin or clopidogrel (Plavix) or both

neuromd2012 :

but you need that MRI first, they are giving you contrast to exclude a tumor or some other cause

neuromd2012 :

like MS

neuromd2012 :

multiple sclerosis, or what I stated earlier

neuromd2012 :

but if this came on suddenly,

Customer:

thank you so very much you answered all my questions.

neuromd2012 :

it suggest vascular

neuromd2012 :

you are welcome

neuromd2012 :

please come back anytime if I can help

neuromd2012 :

Dr Frank T

neuromd2012 :

please rate my service if you can

Customer:

god bless you

neuromd2012 :

thank you, you too

neuromd2012 :

bye
