智能手機和平板電腦的普及，造成越來越多“低頭族”的出現，而過度依賴科技會導致“數碼癡呆癥”等問題，當中以大腦仍在發育的青少年最受影響。近年患記憶障礙的青少年增加，有中學生記不住家門密碼，要查看手機才能進門。

Digital dementia refers to impaired memory and cognitive functioning due to the extended use of digital devices.
“數碼癡呆”指的是由于過度使用數碼設備導致記憶力和認知能力受損。

Digital dementia is when people rely on digital devices like personal computers or cellular phones to the extent that they cannot even recall their own phone numbers.
有時候人們依賴個人電腦或電話等數碼設備，都到了想不起自己的電話號碼是多少的地步，這就是數碼癡呆。

Sufferers are also reported to suffer emotional underdevelopment, with children more at risk than adults because their brains are still growing.
據報道，“數碼癡呆”患者還有情感發育不健全的狀況，兒童比成年人風險更大，因為他們的大腦還處于發育階段。
