Mandy suffers from Alzheimer's and has been quite forgetful and disoriented for at least one year.Accordingly,under the Restatement of Contracts,any agreement she signed during the past 12 months is automatically void because she cannot act in a reasonable manner.

The statement is incorrect. Under the Restatement of Contracts, an agreement is voidable (not automatically void) if one of the parties lacks capacity to contract. Capacity to contract is determined by whether the person understood the nature and consequences of their actions at the time the agreement was made. While Alzheimer's may affect someone's ability to understand the nature and consequences of their actions, this determination must be made on a case-by-case basis and cannot be automatically assumed based on a diagnosis of Alzheimer's alone.
