In modern history, however, TH saw its importation into medical practice where investigations have demonstrated that TH is efficacious in ischemic insults, notably cardiac arrest and hypoxic\u2010ischemic encephalopathy. As well, studies have been undertaken to investigate whether TH can provide benefit in focal stroke (i.e., focal ischemia and intracerebral hemorrhage). However, clinical studies have encountered various challenges with induction and maintenance of post\u2010stroke TH. Most clinical studies have attempted to use body\u2010wide cooling protocols, commonly hindered by side effects that can worsen post\u2010stroke outcomes. Some of the complications and difficulties with systemic TH can be circumvented by using local hypothermia (LH) methods. Additional advantages include the potential for lower target temperatures to be achieved and faster TH induction rates with LH. This systematic review summarizes the body of clinical and preclinical LH focal stroke studies and raises key points to consider for future LH research. We conclude with an overview of LH neuroprotective mechanisms and a comparison of LH mechanisms with those observed with systemic TH. Overall, whereas many LH studies have been conducted preclinically in the context of focal ischemia, insufficient work has been done in intracerebral hemorrhage. Furthermore, key translational studies have yet to be done in either stroke subtype (e.g., varied models and time\u2010to\u2010treat, studies considering aged animals or animals with co\u2010morbidities). Few clinical LH investigations have been performed and the optimal LH parameters to achieve neuroprotection are unknown.<\/jats:p><\/jats:sec><jats:sec><jats:label\/><jats:p>\n<jats:boxed-text content-type=\"graphic\" position=\"anchor\"><jats:graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" mimetype=\"image\/png\" position=\"anchor\" specific-use=\"enlarged-web-image\" xlink:href=\"graphic\/jnc15508-fig-0004-m.png\"><jats:alt-text>image<\/jats:alt-text><\/jats:graphic><\/jats:boxed-text>\n<\/jats:p><\/jats:sec>","DOI":"10.1111\/jnc.15508","type":"journal-article","created":{"date-parts":[[2021,9,8]],"date-time":"2021-09-08T20:36:10Z","timestamp":1631133370000},"page":"128-144","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Targeting focal ischemic and hemorrhagic stroke neuroprotection: Current prospects for local hypothermia"],"prefix":"10.1111","volume":"160","author":[{"given":"Lane J.","family":"Liddle","sequence":"first","affiliation":[{"name":"Department of Psychology University of Alberta  Edmonton Alberta Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna C.
