Malcolm Young's Family Confirms AC/DC Guitarist's Dementia | Rolling Stone

61 Years Old with Demtentia. That's got to be rough. To add insult to injury he attempted and succeeded in overcoming the likely cause of his Dementia.

Young missed AC/DC's Blow Up Your Video World Tour to address his drinking problem.[5] Young eventually got sober and returned to the band. During his absence, he was replaced by his nephew Stevie. It was reported that some fans could not tell Malcolm had been replaced, as Stevie bore a striking resemblance to his uncle.[6]"

Causes of Alcohol Dementia
As the name implies the cause of alcohol dementia is abuse of this substance. Not only does alcohol have a direct impact on brain cells, but those who overuse this mind-altering chemical will often suffer from nutritional deficiencies. It is a lack of Vitamin B1 (thiamine) that can cause the most damage because it leads to brain atrophy. The worst of this damage will occur in the mammillary bodies. The reason why B1 deficiency is such a problem is that this nutrient is required so that the nerve cells can function properly. Those people who abuse alcohol will tend not to eat properly and this accounts for their nutritional deficiency which can continue for many years and cause a great deal of damage.

For an addict to beat his addiction only to have a worse case scenario come to pass is a cruel twist of fate.
