Is leaf drop a sign of a disease?

Usually, leaf drop is a stress response rather than a disease. Check for fungal spots if the leaves look discolored before falling.

Will the leaves grow back?

Yes, once the plant recovers from the stress, it will produce new growth. Be patient and keep the care consistent.
