What causes developmental delays?

Many factors. Developmental delays often just are without much possible explanation. Other times there can be predisposition because of genetics, prematurity, toxin exposure, intrauterine problems, and disease/illness. Interactions with your child of all kinds help development.
Eye of beholder. We have developed expectations of when children should develop skills. Gross motor, fine motor, social, and verbal skills develop at different rates. Each child will develop these skills at their own rate. If they are significantly slower than expected, then they are delayed. It is appropriate for the pediatrician to offer therapy and assistance and to look for causes, and to offer specialist.
Breaking it down. Genetics, biology, & environment, called genotype, phenotype & environtype, interact to cause difficulties in development/academics, behavior & peer interaction. That's why developmental//behavioral pediatrics, a cognitve subspecialty, uses a biopsychosocial model; i.e., we need reliable information about all 3 in order to answer parents' "why, how & when" , as well as, "now, what do we do?".

What conditions cause delays in developmental milestones?

Many causes of delay. There can be many causes for developmental delays. Examples of this would be prematurity, genetic conditions, exposure to drugs, alcohol, lead, or maternal infections. Lack of stimulation can also lead to delays, such as infants who are left in their cribs or infant seats for hours at a time with no interaction. Read more...

What are some causes of teen's gross motor skill developmental delays?

Started when younger. Gross motor delay doesn't start as a teen. Such delays would've been noticed and diagnosed long before (hopefully). However, if there is a loss of gross motor skill then a neurologist must be consulted to look into new onset neurological/neurosurgical problems - sooner rather than later. Read more...

Can sleep apnea in children cause developmental delays?

Learning disabilitie. Sleep apnea has been shown to increase the risk of learning disabilities. There is also a risk of behavioral problems similar to adhd. There area my things that can lead to troubles learning, behaving, and socializing. Be sure all things are investigated and don't rely on one solution to answer all the questions. Read more...
Yes. Sleep apnea causes less rest and sleep which can have multiple effects. It will not stop development but not sleeping and resting could cause development ot slow down a bit. Read more...
Yes. Most of the times this kids by mistake diagnose with adhd and treat them for that instead of their sleep apnea. Read more...
no data on this. Sleep apnea in children has been linked to adhd-like behavior and other behavioral problems, problems with school performance, and poor concentration, but not developmental delays. Children with global delays, especially motor delays, are more likely to have sleep apnea because of problems with their neurologic system. Read more...

Will a hearing problem cause my baby to have a developmental delay?

Yes. Hearing loss is definitely associated with delayed speech, therefore all infants should have their hearing tested at birth, before they leave the hospital. If hearing loss is defected, it should be treated right away. Read more...
Could be. Not only speech delay, but potentially serious emotional and social issues can occur. This can mimic autistic behavior if not recognized and corrected.Fortunately there is routine screening of all newborns in most places for congenital hearing loss, which will allow prevention of these complications. Read more...
YES. Hearing is a crucial part of language development.Expressive and more important receptive language is strongly associated with learning.If your child appears to be having problems speaking , understanding speech or not responding to sounds, please have him/her seen by a doctor and or an audiologist.Long term hearing deficits could create long term sequalae.

If a child's sleep apnea caused developmental delays, the problem was solved with a t&a, how long would it take for them to catch up?

Developmental delay. Sleep apnea cannot be the sole reason for developmental delay. See a neurologist to investigate further. Read more...
Hard to say. To the extent that a child is unrested, lack of attention may cause them to fall behind their peer group in many areas of development. Improvement in their sleep quality may allow for catch-up progress over time, but this is hard to predict.If the child had other ongoing issues, or the sleep apnea was bad enough to produce some impairment, a return to normal may be difficult.

Can tinnitus in a one year old cause developmental delay in speech?

Hearing loss can. Cause speech delay. Tinnitus in a one year old would be difficult to ascertain. Suggest asking the person who made the diagnosis. Congenital tinnitus is not generally associated with either. Read more...

My daughters heart rate dropped 5 hours before having her due to an epidural she is 2 now could that be a cause of developmental delays or leg probs?

No. The low fhr at the time of birth will not cause any neurological deficit later on in life. Our brain is very resilient esp - in uterine. Anoxic/asphyxia insult at the time of delivery can cause lingering effects. Please explore other reasons for her developmental delay. Read more...
No. Without to knowing the exact situation, i cannot comment completely. However, if her heart rate dropped, and they didn't take you immediately to c-section, then i can assume that the heart rate drop was a normal drop secondary to a decrease in your blood pressure, which is a result of the epidural. This normal decrease is not associated with developmental delays or anatomical problems. Read more...
Unlikely. Not knowing the details of your labor and delivery, any thoughts would be speculation. Almost always, transient (coming and going) variations in fetal heart rate are either a normal part of what happens during contractions or due to some obstetrical issues of fetal position, movement, etc. Why not speak with your obstetrician?

Will hearing loss from persistent ear fluid cause developmental delays in my child?

Yes. Hearing impairment certainly delays language development and can affect adversely social skill development in some degrees as well. Read more...
A fluctuating . Conductive hearing loss may cause a child not to discern correct pronunciation of words, causing speech (articulation) delays. There's still debate re: whether it causes delays in receptive (language comprehension) & expressive language ( verbalization of thoughts/ideas). Persistent delays in babbling/talking after pe tubes are placed require evaluation for a neurodevelopmental disorder & therapy. Read more...

Friends baby had a 2mm brain bleed in the frontal lobe. Will this cause any developmental delays?

Brain hemorrhage. Only time will tell! however, babies seem to be more resilient to brain injury secondary to hemorrhage or ischemic insult. Read more...
Not necessarily. Many years ago when ct scans first came out they spent considerable time studying otherwise normal infants to get a sense of what would normally appear on scans. At the time they reported up to 3% of normal infants had evidence of microscopic bleeds when delivered vaginally. Babies have much better recovery than adults to such events. I would look at this finding as unlikely to create problems. Read more...
