‘Childhood Alzheimer’s’ robs teenager of his ability to speak and sing to his favourite song

The mum of a teenager with childhood Alzheimer’s has revealed her heartbreak after it stole his ability to speak - and sing along to his favorite song.

Levi Ormeroid, 19, was able to ride a bike without stabilisers, eat solid foods and colour in pictures when he was a toddler.

He would chatter with friends, could count to 10 and sing the words to his favorite song, Jessie's Girl by Rick Springfield.

Now his eyes light up when he hears the pop classic but he no longer belts out the words after Sanfilippo Syndrome turned the clock back on his mental age.
