Term
|
Definition
| A disorder that interferes with natural motor planning and execution. It makes simple tasks like grabbing a pencil difficult. The hand will fumble around the pen, and then shake if it is able to grasp onto it. |
|

Definition
| Agnosia is the disorder that messes with visual recognition. The patient will often be unable to label what he/she sees but she/he can still describe it without knowing what it is called. |
