My son is 22 months old. He was born 9 weeks early and had the cord around his neck 6 times. At 4 months, he was not tracking so we took him to a pediatric opthamologist who thought he had Cortical Visual Impairment and referred us to a neurologist. His neurologist said that his eyes were fine, but that he was not hearing adequately. So, he ordered an MRI, an EEG, genetic testing, and a BAER. The BAER said he was hearing within normal limits but the MRI showed a right parietal lobe lesion. The doctor suspected Central Auditory Neglect. Over time, it is apparent that my son has a speech delay. At 15 months, he had the expressive speech of a 1 month old and the receptive speech of a 6 month old. He has been in speech therapy for 6 months. However, his behavior is very scary. When he gets upset, he bangs his head on things. It can be the floor, the walls, his toys and recently he has started biting things too when he wants something or is angry. The neurologist said he bangs his head because he can't communicate and if we don't let him get his anger out, he will have more problems later in life. We try to get pillows under his head but he is generally banging his head before we can get to him. Also, if you try to stop him, he will pull your hair, pinch you, smack you and is very mean. He is such a sweet boy when he is not acting like this, but it is like a switch flips and he is completely different. His fits can last up to 45 minutes and there is nothing anyone can do to comfort him. He just screams and bangs his head, and bites. Is this a normal tantrum for a 22 month old boy? I am getting worried. Autism has been mentioned since he was about 9 months old, but I didn't want to do an Autism eval too early in life and label him before therapy was able to help him. Is this normal or should we be seeing someone about this?
