For a 31-week preemie with no complications and normal development as of 2-years-old, how likely are future problems due to prematurity?

For a 31-week preemie with no complications and normal development as of 2-years-old, how likely are future problems due to prematurity?

Very unlikely: A 31-weeker who had no complications and has been normal to age two years, can be looked upon as a normal person just like the full term kids. We are all human, so there is no perfect child. Any future problems are likely due to being a human, and not due to being a 31-weeker. ...Read more

If a child was kept immobile, as in some cases of child abuse, would they miss out on a vital stage in muscle development and have poor motor function/coordination?

If a child was kept immobile, as in some cases of child abuse, would they miss out on a vital stage in muscle development and have poor motor function/coordination?

Yes that can happen: Some of the issue would be mechanical, i.e. Muscle weakness and loss of flexibility/range of motion as the muscles were not used. This is seen in patients after surgeries, injuries, etc. When immobilized. For a child, there is also the issue of muscle and nervous system development and there would likely be some delay and decreased function. Thankfully, with therapy children usually can recover. ...Read more

Can head CT scans in an infant cause radiation and learning disabilities?

Can head CT scans in an infant cause radiation and learning disabilities?

Not exactly: A ct is by definition 'radiation', since it is a series of xrays computer reconstructed as sliced pictures of body tissues. It doesn't cause radiation but exposes the person to radiation. Modern ones may expose one to an amount similar to a transcontinental flight over the usa. Repeat exposure is a current topic of concern, but no specific learning disorder has been identified as connected to this. ...Read more

Can problems arise such as balance issues and hyperthyroidism 40 years after having encephalitis at age 16?

Unlikely: These should prompt a detailed and thorough evaluation from a good clinician. The probability that either was a result of encephalitis at age 16 is almost as remote as winning the lottery without buying a ticket. Go see a doctor. ...Read more

How dangerous is CT scan of brain in a young adult? Wil it cause any problems in the future ? Is it a risk factor for any disease?

How dangerous is CT scan of brain in  a young adult? Wil it cause any problems in the future ? Is it a risk factor for any disease?

CT scan: Ct scans are safe for most people, and the doctors weigh the need for this information vs the exposure to radiation, etc. If the scan includes contrast ("dye") there may be reactions to this -- but most people are not allergic. Your doctors should be checking your history and be ready for any possibility. Please discuss your concerns with the doctors who already know you. ...Read more

I suffered of anxiety during a brain MRI evaluation , and it can not be completed. What others procedures (b.Map, CT scan) are useful for the brain?

I suffered of anxiety during a brain MRI evaluation , and it can not be completed. What others procedures (b.Map, CT scan) are useful for the brain?

Options: It is not uncommon for patients undergoing MRI scans to feel claustrophobic and have to end the test prematurely. If the information needed is important to make a diagnosis or determine treatment, you can try having the procedure with an open mri. Alternatively, if your doctor needs the clarity of the regular MRI images, you may benefit from mild anti-anxiety medications taken before the scan. ...Read more

If a child has problems with attachment, will this lead to other psychiatric problems as an adult?

If a child has problems with attachment, will this lead to other psychiatric problems as an adult?

Likely: Despite the importance of secure attachment (parent-child relationship), events later in life also play an important role in shaping one's emotional health and capacity for intimate human relationship. The children who had an disorganized/disoriented pattern of attachment (abused children, children of parents with major depression, alchol use and bipolar disorder) are at the highest risk. ...Read more
