Cognitive impairments in patients with low grade gliomas and high grade gliomas

Abstract: Objective: The relationship between brain tumors and cognitive deficits is well established in the literature. However, studies investigating the cognitive status in low and high-grade gliomas patients are scarce, particularly in patients with average or lower educational level. This study aimed at investigating the cognitive functioning in a sample of patients with low and high-grade gliomas before surgical intervention. Method: The low-grade (G1, n=19) and high-grade glioma (G2, n=8) patients underwent a det… Show more

“…This non-related word list test measures verbal episodic memory with the involvement of executive functions. This finding is consistent with previous studies in patients with tumors in the frontal lobe region that show reduced memory recall as a consequence of executive difficulties [15], [22]. It should be noted that the patients did not present with aphasia or other language deficits.…”

“…Quanto a faixa etária mais frequente foi entre 31 e 77 anos e o ambos gêneros são mencionados. Bosma et al, 2008;Campennı et al, 2015;Curey et al, 2012;Otten et al, 2012;Prabhu et al, 2010 os autores relataram déficits neuropsicológicos sem utilizar avaliações neuropsicológicas formais, somente por meio de exames de imagem (Amiez et al, 2008;Bauer et al, 2007;Baxendale et al, 2013;Bizzi et al, 2012;Blonski et al, 2012;Bosma et al, 2008;Braun et al, 2008;Campanella et al, 2008;Campennı et al, 2015;Cipolotti et al,2015;Correa, 2008;Curey et al, 2012;Fleming et al, 2014;Fliessbach et al, 2010;Gehring et al, 2009;Gennaro et al, 2006;Giovagnoli et al, 2007;Goebel et al, 2013;Huang et al, 2014;Maesawa et al, 2015;Meguins et al, 2015;Miotto et al, 2011;McDuff et al, 2013;Mu et al, 2012;Noll et al, 2014;Nomura et al, 2013;Otten et al, 2012;Prabhu et al, 2010;Ralph et al, 2010;Satoer et al, 2014;Talacchi et al, 2013) .

“…Quanto à localização dos tumores (Tabela 1), os estudos mostraram que os TC em cuja investigação foi utilizada avaliação neuropsicológica têm ocorrência mais frequente nos lobos temporais (n=12 estudos) e frontais (n=12estudos) (Amiez et al, 2008;Bauer et al, 2007;Baxendale et al, 2013;Bizzi et al, 2012;Braun et al, 2008;Campanella et al, 2008;Campennı et al, 2015;Cipolotti et al, 2015;Correa, 2008;Curey et al, 2012;Fleming et al, 2014;Gennaro et al, 2006;Giovagnoli et al, 2007;Huang et al, 2014;Maesawa et al, 2015;Meguins et al, 2015;Miotto et al, 2011;McDuff et al, 2013;Mu et al, 2012;Noll et al, 2014;Otten et al, 2012;Prabhu et al, 2010;Ralph et al, 2010;Satoer et al, 2014). Em apenas um dos 31 estudos o lobo parietal foi citado como tema central de investigação (Talacchi et al, 2013).…”

“…The precise contribution of tumor grade in cognitive deficits is uncertain to determine. Miotto et al (2011) reported that HGG have greater cognitive impairments than LGG, but both groups were below average and their total IQs were comparable. Surgical removal of HGG has been reported to induce cognitive impairments in some studies (Taphoorn et al, 1994) and not in others (Satoer et al, 2012) inasmuch as the effects of oncologic treatments could combine with those induced by the tumor.…”
