Question: Over the past year, I have noticed significant underdevelopment of the right side of my body, which would obviously correspond to a delay, or a lack of growth in the left hemisphere of my brain. Here are some examples... the left side of my face is more developed than the right (less fat, tighter structure, more facial hair); my hair grows slightly longer on the right side of my head than on the left side of my head, which is the only sign of greater development on the right side of my body than the left obviously due to the fact that my hair is above my central nervous system and my spinal chord; my right testicle is delayed in growth, and will not drop as far as my left testicle when coughing; my right foot is more flat-footed than my left foot, resulting in it not being as straight and alined as my left foot when walking; my finger nails grow longer on my left hand that on my right; and lastly, there are portions of my right thy/leg that are almost completely hairless, as opposed to my left thy/leg, which is developing hair normally. I'm a 6 foot 4 inch, 205 pound, 18 year old male, and the main questions I have are... is this a minor birth defect, considering I did have minor complications during my birth, including c-section, and mucous blocking my air way for several seconds after I was delivered? And... will the left hemisphere of my brain catch up to the left when my body is fully done growing? Thanks!

Brief Answer:
brain doesnt grow at this age

Detailed Answer:
Thanks for writing to health caremagic.
Brain grows only till 6 years. Thereafter it is only increases in connections which happen. No new cells are formed at your age. So it is unlikely that your thinking is correct.
But I think there could be a minor birth insult to the brain which can be responsible for your issue. Do consult a neurologist and get a MRI to really identify any problems in brain. Some problems like birth insult to brain may be irreversible at this age, but if there are other causes identified in MRI like lesion, edema etc, these can be medically treated.
Wishing you great health.

Hi. I am a thirty five year old female with a history of depression. 2 years ago I had a couple of seizure like episodes while still concious but my mri came out normal. I am 5 feet 3 inches tall, weigh 135 lbs and in overall good health.
My concern is I experience body tremors while asleep that wake up my husband. Im not usually aware of this happening since I am deep asleep. I wonder what would cause that. Since the seizure episodes, my hands shake a lot during waking hours when holding my phone or using keys to open a lock. I would like to know what this means. Thanks.

My nine month old has unilateral hearing loss and as a result of an MRI we have been told that he has deformities of the semi curricular canals on both the left and right side. I understand the hearing loss and the implications.What I don't understand is what will the likely long term implications be as a result of the semi circular canal deformities. We have been told that he has approximatively have the semi curricular canals on each side

yes thank you. My husband a 43 y.o. male has been hospitalized a second time noe within the last 3 months. the first time they DX him with guillian barre syndrome. they treated with IVIG for 5 consecutive days and then he remained in hospital a total of 9 days until he could walk and then was discharged. this time, s/s started the same as before. N/T in bilateral feet that migrated quickly up to knees and then tohips and then to elbows and wrists. Then intense burning ache in the joints that followed the same progression. MRI show lesions in the brain, none in spinal cord or brain stem. Lumbar puncture showed only elevated proteins (67). they checked for lymes, encephalitis, meningitis.ets... The first time in Novenmber he last all pheripheral reflexes. This time they sre dull only at this point. I am concerned that they are missing something. My husband states the pain is 9/10, and the only meds that help are Neurontin and toradol. Narcotocs and muscle relaxers do not help at all. We questioned CIDP, MS, transverse myelitis, and they have no answers. They havedone another MRI of brain and brain stem/ neck area. We do not know the results yet, and they are questioning whether or not to do another lumbar puncture... I have requested west nile test and tey just ignore me...I have been an RN for 24 years as well.

My mother is 89 and on hospice care for advanced A.D. she has developed, over past year, an indentation on the top of her skull running left to right about three inches back from the front of the scalp. She has several large nodules on her thyroid, but her endocrinologist declined to pursue with needle biopsy or surgery due to her age and advanced disease, A.D. what do you think could be the cause of the changes in the top of her skull, indentation. She also has had significant loss in brain mass in past 12 years per MRI studies ren years apart.
