Abstract
ObjectivesThis study investigates the levels of 15 bioelements (calcium, copper, chromium, sodium, iron, magnesium, manganese, zinc, cobalt, selenium, molybdenum, vanadium, potassium, boron, and lithium) in the hair species of Jordanian stutterer. MethodsThe subjects of the study included 25 cases of stuttering, and 25 normal children (age and sex matched). The severity of stuttering (low, moderate, and severe) were assessed using Stuttering Severity Instrument, Fourth edition (SSI-4). Hair samples of subjects were cut, washed, dried, physically degraded, hydrolyzed, and analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). ResultsResults indicated that the levels of bioelements (Calcium, Copper, Chromium, Magnesium, Manganese, Cobalt, Selenium, Molybdenum, Vanadium, Boron, and Lithium) were significantly lesser in the hair samples of stuttering group than the control group. ConclusionThe findings of the current study could support the use of biochemical analyses as diagnostic biomarker for stuttering.
