We determined the association between past or current smoking versus lifetime non-smoker status on the volumes of the basal forebrain determined from volumetric MRI scans. Hippocampus volume was used as a control region. Significant effects were controlled for mediating or moderating effects of respiratory and cardiovascular morbidity.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    In cognitively healthy individuals and early MCI, past or current smoking was significantly associated with smaller basal forebrain volume. This effect was independent from age, sex, or cardiovascular or respiratory morbidity. Hippocampus volume was not associated with smoking. In late MCI and AD dementia, smoking was not associated with basal forebrain or hippocampus volumes.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Our findings suggest that chronic nicotine exposure through smoking may lead to atrophy of cholinergic input areas of the basal forebrain. This effect may account for an increased risk of AD dementia onset with smoking by exhausting the cholinergic system reserve capacity.\n                  <\/jats:p>","DOI":"10.3233\/jad-151100","type":"journal-article","created":{"date-parts":[[2016,6,10]],"date-time":"2016-06-10T13:44:57Z","timestamp":1465566297000},"page":"1443-1451","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Association Between Smoking and Cholinergic Basal Forebrain Volume in Healthy Aging and Prodromal and Dementia Stages of Alzheimer\u2019s Disease"],"prefix":"10.1177","volume":"52","author":[{"given":"Stefan","family":"Teipel","sequence":"first","affiliation":[{"name":"Department of Psychosomatic Medicine, University of Rostock, Rostock, Germany"},{"name":"DZNE, German Center for Neurodegenerative Diseases, Rostock, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel J.","family":"Grothe","sequence":"additional","affiliation":[{"name":"DZNE, German Center for Neurodegenerative Diseases, Rostock, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"for the Alzheimer\u2019s Disease Neuroimaging Initiative","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,4,12]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1460-9568.2006.05050.x"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.drugalcdep.2013.08.020"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpsychires.2013.12.004"},{"key":"e_1_3_2_5_2","article-title":"Assessment of the effect of cigarette smoking on regional brain volumes and lesion load in patients with clinically isolated syndrome","author":"Durhan G","year":"2015","unstructured":"DurhanG, DikerS, HasAC, KarakayaJ, KurneAT, KarabudakR, OguzKK (2015) Assessment of the effect of cigarette smoking on regional brain volumes and lesion load in patients with clinically isolated syndrome.
