Dressing apraxia is a significant functional deficit in corticobasal syndrome (CBS), characterized by the inability to properly dress oneself despite intact motor strength and sensation. This deficit emerges from the visuospatial and parietal lobe dysfunction that is hallmark of CBS and represents a major contributor to loss of independence in activities of daily living (ADLs).
Dressing difficulties in CBS occur in approximately 50-70% of patients, with dressing apraxia specifically occurring in around 30-40%. This makes it one of the more disabling functional deficits in CBS, contributing significantly to caregiver burden and loss of independence.
| Region | Function | CBS Involvement |
|---|---|---|
| Inferior Parietal Lobule (areas 39, 40) | Primary — body schema, spatial orientation | Most critical |
| Posterior Parietal Cortex (BA 7) | Spatial processing, body schema | Primary |
| Superior Parietal Lobule | Visuomotor integration | Primary |
| Supplementary Motor Area | Motor planning for complex sequences | Secondary |
| Premotor Cortex | Motor execution planning | Secondary |
| Corpus Callosum | Interhemispheric integration | Contributes |
As with other CBS deficits, dressing difficulties often present asymmetrically:
Sequencing Errors
Spatial Orientation Errors
Neglect-Related Errors
Bilateral Coordination
| Garment | Typical Problem |
|---|---|
| Shirt/T-shirt | Putting wrong arm in first, inside-out |
| Pants | Inverting, confused front/back, wrong holes |
| Socks | Difficulty positioning on feet |
| Buttons | Unfastened, misaligned, wrong sequence |
| Jacket | Asymmetric sleeve placement |
| Shoes | Wrong foot, difficulty with laces |
Patients with dressing apraxia often describe their affected limb as feeling "foreign" or "belonging to someone else" — a phenomenon related to the alien limb syndrome often seen in CBS. This body schema disturbance contributes to dressing difficulties by creating a disconnect between the mental representation of the body and the actual limb.
| Condition | Dressing Apraxia | Pattern |
|---|---|---|
| CBS | Common (30-40%) | Asymmetric, early |
| PSP | Less common (15-20%) | Bilateral, late |
| PD | Uncommon | Usually only with dementia |
| FTD | Variable | Frontal variant may show |
| AD | Moderate-severe disease | Bilateral |

Dressing assistance contributes significantly to caregiver burden:
Compensatory Strategies
Environmental Modifications
Sequencing Cues
Training Approaches
| Issue | Solution |
|---|---|
| Buttons | Replace with Velcro, elastic |
| Socks | Use sock aids |
| Pants | Elastic waistbands |
| Shoes | Slip-on, elastic laces |
| Shirts | Pull-over, front-opening |
| Coats | Zipper pulls |
