What Causes Tics In Children
Antenatal factors : Some syndromes cause autistic spectrum disorder & intellectual disability. Chromosomal microarrays find genetic errors in ~15% of kids with ASD. Maternal low folate (folic acid) levels at conception, rubella, "flu", obesity, advanced age & alcohol/drug use from 3 wks.post-conception-term are some epigenetic factors that alter function, but not structure or sequence, of fetal genes & increase risk of ASD. ...Read more
Genetics/external fr: There is ample evidence that true asthma is genetically linked to the issues of allergy & eczema & frequency is higher when one or both parents are affected. Lower respiratory tract viruses often trigger both infectious wheezing & that of true asthma early on with infectious wheezing subsiding after 3-4y. Allergies often co-exist but less than 5% of events are allergy driven alone. ...Read moreSee 2 more doctor answers
Genes + environment: To develop an allergy, you need a genetic predisposition. For example, children at highest risk of developing allergic asthma are those whose parents have asthma. Also necessary is multiple exposures to the allergen. The strongest predictor of developing allergies in the future is having allergic disease now (for example, a child with eczema has increased chance of developing asthma). ...Read moreSee 1 more doctor answer
Hydrocephalus: It is blockage of the flow of fluid in the brain. Meningitis, tumor, traumatic head injury, subarachnoid hemorrhage, cranial surgery, or medications have been implicated. In children it can be due to premature birth or genetic defects - that blocks flow (aqueductal stenosis). Apparently, often the cause is not determined. With early treatment "many lead normal lives with few limitations.". ...Read moreSee 1 more doctor answer
UTI, small bladder &: Diabetes melitus, reverse circadian rythmn (producing more urine at night than by day. Diabetes insipidus, renal or central where kidneys lose ability to concentrate urine & thus too much urine is produced. Multiple sclerosis, neurogenic bladder dysfunction. All are among causes. Suggest you see a urologist. ...Read more
Duration: Tics come in many forms--vocal or motor, transient or chronic, simple or complex. Transient tics (vocal or motor) last only for a few days or weeks or occur only occasionally, usually under increased stress; they are quite common especially in boys 6-9 years old. They are benign, do not require treatment, and nearly always resolve spontaneously. A eye or cheek twich is a common example. ...Read moreSee 2 more doctor answers
Pharmacology: Tics are repetitive, involuntary, stylized, motor movements involving a single or complex group of muscles. Chemicals that are stimulatory in nature, such as caffeine or methylphenidate, may excite muscle fibers to contract more easily. Brain control of muscle firing may also be increased with these substances. Tics are worsened by stimulants, not caused by them. See my health guides on panda's. ...Read moreSee 2 more doctor answers
Sometimes genetics: With retinoblastoma, 40% of children have a genetic form: one copy of the RB1 gene is changed in every cell in the body at birth. If the 2nd copy of the gene undergoes a change, a retinoblastoma tumor can develop. Most children with retinoblastoma do not have the genetic form & spontaneously develop 2 RB1 mutations in an immature cell. Scientists don't know how or why it occurs in these childen. ...Read more
Several causes: Toxic gas inhalation,acute epiglottitis,inhaled foreign body laryngeal tumors pharyngeal tumors, paratracheal compression by enlarged lymph nodes, vocal cord palsy, granulation tissue in airway from previous intubation or tracheostomy are few causes. Something that causes partial obstruction to airway. ...Read more
Stress and anxiety: Nightmares are sleep disruptions that include frightening content and are especially common in early childhood. Often these experiences are influenced by stressors that occur during waking hours. The course and development of nightmares are largely dependent on developmental level and are present throughout childhood (journal of clinical child psychology, 2000). ...Read moreSee 2 more doctor answers
Formed long ago: The vast majority of brain cysts are congenital, meaning they formed when your brain was forming as an embryo and are innocent. The benign brain cysts dont change over time and ar nothing to worry about. Frequently found when you have a brain scan performed for an unrelated reason. ...Read more
Here are some ...: The function of bladder control & stability is still varying over lifetime despite being toilet-trained and more noticeable at both ends of life - the first 1-3 yrs and the twilight years, largely resulting from inadequacy of controlling ability of central nerve. During these 2 ends of life, one is more prone or susceptible to the occurrence of inciting factors like UTI, poor sleep, tiredness, etc ...Read moreSee 1 more doctor answer
Infestor vs infector: School kids oft have a relaxed pattern of personal hygene & well developed pattern of sharing.Things that infest (lice/pinworms/scabies mite) are all possibilities for school transmition.Things that infect (bacteria/virus/fungus/etc) are also spread in this close and relaxed environment.As they age & acquire better self monitoring & hygene, the infestors are less prominent. ...Read moreSee 1 more doctor answer
