Why can't dopamine cross the blood brain barrier but l-dopa can? Levodopa can cross the BBB and is less lipid soluble then dopamine, so dopamine should be able to cross the BBB more easily then l-dopa, but for some re...
Both L-Dopa and Dopamine are polar molecules and thus hydrophilic. They are solvable in water but not in lipids, so they are not able to cross the Blood-brain barrier on their own. The difference is that L-Dopa has a transport protein (SLC7A5) that allows it to pass through the Blood-brain barrier, ...

79岁男性帕金森10年DBS手术治疗可以维持,开始时间2004;服用Carbidopa-levodopa 25/100 从4片每天4小时一片逐渐加到10片/天;同时未服用其他药物最初胳膊刷牙困难,肢体僵硬。
一般来讲,对早期的帕金森氏病患者应首先采取药物治疗,药物治疗3~5年后效果减退,出现了“开、关” 波动现象,异动症和“剂末”恶化效应,病情会变得更加难以控制,这时候就应考虑外科治疗了。
