Maybe a comprehensive neuropsychological test battery like the NAB (Petermann, Jäncke & Waldmann, 2016) would be helpful in providing a broad cognitive profile!
During my research for PhD Thesis about neuropsychological findings in children with focal epilepsy I used different neuropsychological tests regarding function I have tested.
For attention I used TP test (origin from Slovenia)
For visual memory and perception: Rey -Osterreith complex figure
For verbal memory Selective Reminding Test (Buschke et al 1974)
Boston Naming Test, TOKEN test and verbal fluency for language
