Please extract a list from this paragraph of the brain regions impacted by alcohol-related dementia and separate them using commas.

Alcohol-related dementia, also called alcohol-related brain damage, occurs as a result of excessive use of alcohol particularly as a substance abuse disorder. Different factors can be involved in this development including thiamine deficiency and age vulnerability.[75][76] A degree of brain damage is seen in more than 70% of those with alcohol use disorder. Brain regions affected are similar to those that are affected by aging, and also by Alzheimer's disease. Regions showing loss of volume include the frontal, temporal, and parietal lobes, as well as the cerebellum, thalamus, and hippocampus.[76] This loss can be more notable, with greater cognitive impairments seen in those aged 65 years and older.[76]
