Provided are methods for the detection of GDF11 in a subject having or suspected of having a mood and/or anxiety disorder, comprising providing a sample from a subject having or suspected of having a mood and/or anxiety disorder; contacting the sample with a GDF11-binding molecule; and detecting bound GDF11. Also provided are methods of diagnosing or characterizing a mood and/or anxiety disorder in a subject, comprising providing a sample from a subject; contacting the sample with a GDF11-binding molecule; detecting bound GDF11; and comparing the levels of detected bound GDF11 to healthy reference levels. Also provided are methods of treating or preventing a mood and/or anxiety disorder and/or accelerated aging in a subject in need thereof, comprising administering to the subject an agent or composition which increases the levels of GDF11 polypeptide in the subject.

The present invention provides combinations of biomarkers that can be used in the diagnosis and differentiation of bipolar disorder and schizophrenia. The present invention therefore provides methods of differentiating, diagnosing and treating bipolar disorder and schizophrenia, by examining relevant proteins and RNA in a patient sample.

Method of dosing and treating patients with a psychedelic, by administering a psychedelic at a dose of a microdose, minidose, psychedelic dose, good effect dose, ego-dissolution dose, or cardiovascular safe dose, and producing maximum positive subjective acute effects that are known to be associated with more positive long-term outcomes and minimizing negative acute effects. Method of determining a dose of a psychedelic for an individual, by administering a dose of a psychedelic to the individual of a microdose, minidose, psychedelic dose, good effect dose, ego-dissolution dose, or cardiovascular safe dose, determining positive acute effects and negative acute effects in the individual, and adjusting the dose to provide more positive acute effects than negative acute effects in the individual. Methods of treating psychiatric conditions or providing therapy. Method of defining therapeutic doses of a psychedelic in clinical trials. Method of monitoring individuals for depression after treatment with LSD.

The present invention provides, inter alia, methods for treating or ameliorating the effects of a disorder, such as schizophrenia or bipolar disorder, by increasing or decreasing proline levels. Further provided are methods of predicting and monitoring the clinical response in a patient, and diagnostic systems for identifying a patient likely to benefit from proline modulation.

Described herein are methods for identifying mitochondrial defects using metabolomics and genetic analyses and using this information to stratify patients and to correct for metabolic defects in a precision medicine approach. One embodiment is a method for isolating and analyzing samples containing one or more mitochondrial biomarker metabolites or genetic markers useful for the analysis, identification, stratification or classification, and treatment of metabolic changes associated with a CNS or neuropsychiatric disease in a subject and therapies useful for the treatment thereof. In one aspect, the biomarker metabolites comprise mitochondrial metabolites including acylcarnitines and endocannabinoids and the genetic analyses focus on metabolic enzymes or transport mechanisms.

The present invention provides combinations of biomarkers that can be used in the diagnosis and differentiation of bipolar disorder and schizophrenia. The present invention therefore provides methods of differentiating, diagnosing and treating bipolar disorder and schizophrenia, by examining relevant proteins and RNA in a patient sample.

In some embodiments, methods of inhibiting, ameliorating, reducing the severity of, treating, reducing the likelihood of, or preventing social isolation stress or symptoms thereof in a subject in need thereof are described. In some embodiments, methods of determining a risk of social isolation stress in a subject are described.

The present invention relates to a method for treating a neurological disease in a subject including administering to the subject a pharmaceutical composition of a eukaryotic elongation factor 2 kinase (eEF2K)-inhibiting compound.

Methods for treating depression in, and decreasing a dose of ketamine given to, a subject in need thereof, comprising, administering a CaMKII inhibitor are provided.

A method of dosing and treating patients with a psychedelic, by administering a psychedelic at a dose of a microdose, minidose, psychedelic dose, good effect dose, ego-dissolution dose, or cardiovascular safe dose, and producing maximum positive subjective acute effects that are known to be associated with more positive long-term outcomes and minimizing negative acute effects. A method of determining a dose of a psychedelic for an individual, by administering a dose of a psychedelic to the individual of a microdose, minidose, psychedelic dose, good effect dose, ego-dissolution dose, or cardiovascular safe dose, determining positive acute effects and negative acute effects in the individual, and adjusting the dose to provide more positive acute effects than negative acute effects in the individual. Methods of treating psychiatric conditions or providing therapy. A method of defining therapeutic doses of a psychedelic in clinical trials. A method of monitoring individuals for depression after treatment with LSD.
