Data were compared with 49 healthy controls. Cognition was measured with the Edinburgh Cognitive and Behavioral ALS Screen.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Evolution and features of cognitive profile of patients with motor predominant ALS were distinctly different from patients with behavioural FTD with regard to number and degree of affected cognitive domains. Also, in ALS mostly minus symptoms evolved after physical symptom onset whereas in ALS-FTD plus and minus symptoms were reported with an onset before physical degradation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Evolution of cognitive and behavioural profile in patients with motor predominant ALS is distinctly different from those psychocognitive findings in patients with behavioural variant dementia.
