We systematically reviewed VBM studies of Alzheimer's disease (AD) and mild cognitive impairment (MCI), specifically focusing on grey matter (GM) atrophy in the frontal lobe.  Methods:  Two searches were performed on the Pubmed database. A set of exclusion criteria was applied to ensure the selection of only VBM studies that directly investigated GM volume abnormalities in AD and\/or MCI patients compared to cognitively normal controls.  Results:  From a total of 46 selected articles, 35 VBM studies reported GM volume reductions in the frontal lobe. The frontal subregions, where most of the volume reductions were reported, included the inferior, superior and middle frontal gyri, as well as the anterior cingulate gyrus. We also found studies in which reduced frontal GM was detected in MCI patients who converted to AD. In a minority of studies, correlations between frontal GM volumes and behavioural changes or cognitive deficits in AD patients were investigated, with variable findings.  Conclusion:  Results of VBM studies indicate that the frontal lobe should be regarded as an important brain area when investigating GM volume deficits in association with AD. Frontal GM loss might not be a feature specific to late AD only. Future VBM studies involving large AD samples are warranted to further investigate correlations between frontal volume deficits and both cognitive impairment and neuropsychiatric symptoms.<\/jats:p>","DOI":"10.1590\/s1980-5764-2016dn1002006","type":"journal-article","created":{"date-parts":[[2016,6,25]],"date-time":"2016-06-25T08:48:14Z","timestamp":1466844494000},"page":"104-112","source":"Crossref","is-referenced-by-count":25,"title":["Voxel-based morphometry in Alzheimers disease and mild cognitive impairment: Systematic review of studies addressing the frontal lobe"],"prefix":"10.1590","volume":"10","author":[{"given":"Lu\u00eds Gustavo","family":"Ribeiro","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geraldo","family":"Busatto Filho","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"387","DOI":"10.1016\/S0140-6736(06)69113-7","article-title":"Alzheimer's Disease","volume":"368","author":"Blennow K","year":"2006","journal-title":"Lancet"},{"key":"ref2","series-title":"World Alzheimer report 2010: the global economic impact of dementia","year":"2010"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1016\/j.jns.2012.02.010","article-title":"Voxelwise Meta-analysis of Gray Matter Anomalies in Alzheimer's Disease and Mild Cognitive Impairment Using Anatomic Likelihood Estimation","volume":"316","author":"Yang J","year":"2012","journal-title":"J Neurol Sci"},{"key":"ref4","first-page":"429","article-title":"The frontal lobes In: Linsmeier C, Brooks B, Kruger J, et al.
