Hi doctor. my mother complaining of (dropping stuffs) once and then, from her rt hand, only small & light in weight stuffs like (keys, phone..). and i saw that happening twice yesterday. no problems with the heavy weight things, only the leight ones.. wha

There are a number: ...of possibilities. She might have lost the feeling in that hand. She might have weakness in the smaller muscles of the hand that control what we call "fine motor coordination." ( Like what you need when writing). Rarely, a person's brain sort of "forgets" that the hand is there. She definitely needs to get medical care. It could be anything from a pinched nerve to a mini-stroke.

Stroke?: This could be a very early sign of cerebral ischemia and imminent stroke. Have her checked ASAP. Hope all goes well.

Carpal Tunnel Syndrm: In severe cases of Carpal Tunnel Syndrome, motor involvement leads to complaints of weakness or clumsiness when using the hands, such as difficulty holding objects, turning keys or doorknobs, buttoning clothing, or opening jar lids. Clinical signs may include weakness of thumb abduction and opposition, and atrophy of the thenar eminence (base of the thumb).
