Noninvasive, regional brain thermal stimuli for the treatment of neurological disorders
Apparatuses and methods for treating neurological and/or neuropsychiatric disorders are by application of thermal energy to the patient's forehead region, for example, by maintaining a target temperature or temperature range to the forehead of a patient for a time period. In particular, described herein are regional brain cooling mechanisms to treat neuropsychiatric disorders such as depression, anxiety, and autism.

13. The method of claim 1 , wherein maintaining the temperature of the thermal transfer region comprises maintaining the temperature while the patient is awake.
14. The method of claim 1 , wherein the maintaining further comprises cooling the thermal transfer region for a predetermined amount of time using one or more of: a thermal transfer fluid, a chemical heating or cooling element, a thermoelectric temperature regulator, and a joule heating element.
15. A method for treating a neurological disorder in a patient, the method comprising:
applying noninvasive, regional brain cooling to a region of a patient's head over a forehead and a temporal region of the patient's skull to locally cool the patient's forehead and the patient's temporal region by applying a temperature of between 10° C. and 28° C.; and
maintaining the applied temperature between 10° C. and 28° C. to reduce brain metabolism in one or more of the patient's frontal cortex, prefrontal cortex and temporal cortex to treat the neurological disorder,
wherein the neurological disorder is one of: posttraumatic stress disorder (PTSD), obsessive compulsive disorder (OCD), autism, depression, anxiety, and attention deficit hyperactivity disorder (ADHD).
16. The method of claim 15 , wherein the neurological disorder is one of: depression, anxiety, and attention deficit hyperactivity disorder (ADHD).
17. The method of claim 15 , wherein the neurological disorder is posttraumatic stress disorder (PTSD).
18. The method of claim 15 , wherein the neurological disorder is Obsessive Compulsive Disorder (OCD).
19. The method of claim 15 , wherein the neurological disorder is autism.
20. The method of claim 15 , wherein maintaining comprises maintaining the temperature of the thermal transfer region within the target temperature range for a first predetermined time period of between 10 minutes and 12 hours.
21. The method of claim 15 , wherein the maintaining the applied temperature comprises maintaining the temperature for a predetermined time period of between 10 minutes and 4 hours.
22. The method of claim 15 , wherein the maintaining the applied temperature comprises maintaining the temperature for a first predetermined amount of time and then maintaining the applied temperature within a target temperature range of 25 to 36° C. for a second predetermined amount of time.
23. The method of claim 15 , wherein the maintaining the applied temperature comprises maintaining for a predetermined amount of time that is greater than 15 minutes for at least once a day for between 1-12 weeks.
24. The method of claim 15 , wherein maintaining the applied temperature comprises maintaining for a predetermined amount of time that is greater than 15 minutes for more than 2 times per week.
25. The method of claim 15 , wherein maintaining the applied temperature comprises maintaining the applied temperature while the patient is awake.
26. The method of claim 15 , wherein maintaining comprises cooling for a predetermined amount of time using one or more of: a thermal transfer fluid, a chemical heating or cooling element, a thermoelectric temperature regulator, and a joule heating element.
27. A method for treating a neurological disorder in a patient, the method comprising:
securing a thermal transfer region of an applicator in contact with the forehead of the patient so that the thermal transfer region does not contact the periorbital region of the patient's face; and
maintaining the temperature of the thermal transfer region within a target temperature range to modify brain metabolism; and
thereby treating the neurological disorder,
wherein the neurological disorder is one of depression, anxiety, posttraumatic stress disorder (PTSD) attention deficit hyperactivity disorder (ADHD), Obsessive Compulsive Disorder (OCD), and autism.
28. The method of claim 27 , wherein the neurological disorder is one of: depression, anxiety, posttraumatic stress disorder (PTSD) and attention deficit hyperactivity disorder (ADHD).
