The Multiple Sclerosis Performance Test (MSPT): An iPad-Based Disability Assessment Tool
Published on: June 30, 2014
Abstract:
Primary progressive multiple sclerosis (MS), comprising 10% to 15% of all cases of MS, is characterized by an insidious progression from the onset of disease, making it clinically distinct from the commonest form, relapsing remitting MS. Making the diagnosis can be challenging, and misdiagnosis and delay in diagnosis are common. Although no effective treatments are currently known, insights into the pathogenesis of this phenotype aid in understanding the processes that drive progression in all forms of MS.
Insights
Primary progressive multiple sclerosis (PPMS) presents a diagnostic challenge due to its insidious progression. Understanding PPMS pathogenesis offers insights into multiple sclerosis progression overall.
Area of Science:
- Neurology
- Neuroimmunology
- Clinical Neuroscience
Background:
- Primary progressive multiple sclerosis (PPMS) accounts for 10-15% of all multiple sclerosis cases.
- PPMS is characterized by insidious disease progression from onset, distinguishing it from relapsing-remitting MS.
- Diagnosis of PPMS can be challenging, frequently leading to misdiagnosis and delayed treatment initiation.
Purpose of the Study:
- To highlight the diagnostic difficulties associated with primary progressive multiple sclerosis.
- To underscore the importance of understanding the pathogenesis of PPMS.
- To elucidate how insights into PPMS can inform the broader understanding of multiple sclerosis progression.
Main Methods:
- Review of clinical characteristics differentiating PPMS from other MS forms.
- Analysis of diagnostic challenges and common pitfalls.
- Examination of current understanding of PPMS pathogenesis.
Main Results:
- PPMS exhibits a distinct, gradual progression pattern from disease onset.
- Diagnostic delays and misdiagnoses are prevalent in PPMS cases.
- Pathogenic insights into PPMS are crucial for understanding disease progression across all multiple sclerosis phenotypes.
Conclusions:
- Despite the absence of effective treatments, understanding PPMS pathogenesis is vital.
- Insights gained from studying PPMS contribute to a comprehensive understanding of multiple sclerosis.
- Accurate and timely diagnosis of PPMS remains a significant clinical challenge.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
