长期吃过敏药会造成痴呆。

in recent years, concerns have been raised about the potential link between the long-term use of anticholinergic medications like Benadryl and the development of dementia in older adults.

Be aware, too, that first-generation antihistamines typically are not recommended for adults 65 and older. That's because they have something called anticholinergic properties. Research suggests those properties might raise the risk of dementia. Antihistamines may be helpful to ease sleeplessness once in a while. But don't rely on them to treat chronic insomnia.

如果是女的建议先看OBGYN排除更年期焦虑症，楼主可在家庭医生那抽血检查排查过VD，VB12，镁，叶酸，甲状腺等检查，有的人属于这些造成睡眠不好，有的属于呼吸暂停综合征（楼主有打呼建议看耳鼻口sleep专科ent sleep specialist，有的属于更年期焦虑症（看OBGYN）。

以上都排查完，那么楼主可以因为焦虑看看精神科同时辅助心理科，
