Ideomotor apraxia (IMA), although clearly present in CBD, often manifests atypically due to the additional presence of bradykinesia and rigidity in those individuals exhibiting the disorders. The IMA symptom in CBD is characterized by the inability to repeat or mimic particular movements (whether significant or random) both with or without the implementation of objects. This form of IMA is present in the hands and arms, while IMA in the lower extremities may cause problems with walking. Those with CBD that exhibit IMA may appear to have trouble initiating walking, as the foot may appear to be fixed to floor. This can cause stumbling and difficulties in maintaining balance. IMA is associated with deterioration in the premotor cortex, parietal association areas, connecting white matter tracts, thalamus, and basal ganglia. Some individuals with CBD exhibit limb-kinetic apraxia, which involves dysfunction of more fine motor movements often performed by the hands and fingers.
