Which of the following can be observed in ALS?

Explanation:
ALS involves degeneration of motor neurons, leading to both upper and lower motor neuron signs. When the bulbar region is affected, the lower motor neurons that control the tongue degenerate, resulting in tongue atrophy with fasciculations and weakened tongue movements. This bulbar lower motor neuron involvement is a classic feature of ALS, so tongue atrophy stands out as a characteristic observation among the options. While hand weakness and hyperreflexia can also occur due to limb and upper motor neuron involvement, seizures are not typical in ALS.
