METHODS FOR THE TREATMENT OF NEUROLOGICAL DISORDERS

1 . A method of treating a neurological disorder in a subject in need thereof, the method comprising administering a fatty acid synthase (FASN) inhibitor in an amount sufficient to suppress toxicity in a cell related to protein misfolding and/or aggregation.

2 . A method of suppressing toxicity in a cell related to protein misfolding and/or aggregation in a subject, the method comprising contacting a cell with a FASN inhibitor.

3 . The method of claim 1 , wherein the toxicity in the cell is related to protein aggregation related to misfolding of a protein.

4 . The method of claim 1 , wherein the toxicity in the cell is related to misfolding and/or aggregation of α-synuclein or ApoE4.

5 - 6 . (canceled)

7 . A method of treating a neurological disorder in a subject in need thereof, the method comprising:

(a) determining the expression level of α-synuclein, ApoE4, or an undesired form thereof in the subject;

(b) administering an effective amount of a FASN inhibitor to the subject if the level of α-synuclein, ApoE4, and/or the undesired form thereof is greater than a predetermined level.

8 . A method of treating a neurological disease in a subject in need thereof, wherein the subject has an elevated level, or is predicted to have an elevated level of α-synuclein, ApoE4, or an undesired form thereof the method comprising administering an effective amount of a FASN inhibitor to the subject.

9 . The method of claim 8 , wherein the subject is predicted to have an elevated level of α-synuclein, ApoE4, and/or an undesired form thereof based on genetic markers.

10 . The method of claim 1 , wherein the subject carries one or two copies of the ApoE4 allele.

11 . (canceled)

12 . The method of claim 1 , wherein the neurological disorder is Alzheimer's disease (AD), mild cognitive impairment (MCI), cerebral amyloid angiopathy (CAA), dementia associated with Down syndrome, Parkinson's disease (PD), dementia with Lewy bodies, amyotrophic lateral sclerosis or Lou Gehrig's disease, Alpers' disease, Leigh's disease, Pelizaeus-Merzbacher disease, Olivopontocerebellar atrophy, Friedreich's ataxia, leukodystrophies, Rett syndrome, Ramsay Hunt syndrome type II, Down's syndrome, multiple sclerosis.

13 - 15 . (canceled)

16 . The method of claim 1 , wherein the neurological disorder is Parkinson's disease (PD), dementia with Lewy bodies, pure autonomic failure, multiple system atrophy, incidental Lewy body disease, pantothenate kinase-associated neurodegeneration, Gaucher disease, or the Parkinsonism-dementia complex of Guam.

17 . The method of claim 16 , wherein the neurological disorder does not comprise a PINK1 mutation.

18 . (canceled)

19 . The method of claim 1 , wherein the neurological disorder is AD, Alexander disease, amyotrophic lateral sclerosis (ALS), a prion disease, Huntington's disease, Machado-Joseph disease, Pick's disease, or frontotemporal dementia.

20 . The method of claim 19 , wherein the prion disease is Creutzfeldt-Jakob disease.

21 . The method of claim 1 , wherein the neurological disorder is a neurodegenerative disorder.

22 . The method of claim 21 , wherein the neurodegenerative disorder is Alpers' disease, ataxia telangectsia, Canavan disease, Cockayne syndrome, corticobasal degeneration, Kennedy's disease, Krabbe disease, Pelizaeus-Merzbacher disease, primary lateral sclerosis, Refsum's disease, Sandhoff disease, Schilder's disease, Steele-Richardson-Olszewski disease, tabes dorsalis, vascular dementia, or Guillain-Barre Syndrome.

23 . The method of claim 1 , wherein the neurological disorder is an ApoE-associated neurodegenerative disorder.

24 . The method of claim 23 , wherein the ApoE-associated neurodegenerative disorder is AD, vascular cognitive impairment, cerebral amyloid angiopathy, traumatic brain injury, or multiple sclerosis.

25 . The method of claim 24 , wherein the ApoE-associated disorder is AD.

26 - 28 . (canceled)
