Psychological Evaluations

Diagnostic psychological evaluations are used to determine if an individual exhibits any signs of specific psychological diagnosis. As there are no lab tests to confirm mental illness, psychological testing can be essential for arriving at an accurate diagnosis and for the purposes of treatment planning.  Psychological testing is used to help confirm common psychological disorders such as ADHD, bipolar disorder, anxiety disorders and many others.  Our mental health providers also have the capability to test for intellectual disability, learning disorders and other similar problems.


Neuropsychological Evaluations

This type of evaluation can be useful for doctors to understand how an injury or illness is affecting the function of the brain and can be used to help find the right diagnosis when the problem may not be clear, as well as to detail a comprehensive treatment plan.

Psychiatric Medication Management

As part of a comprehensive treatment plan for mental wellness, this sometimes includes the need for psychotropic medications.  Our mental health team can provide psychiatric medication management to include commonly used medications as well as specialized injectable formulas. We can also provide esketamine treatment for treatment resistant depression. A dedicated lab is available for analysis of blood draws and urinalysis for precise prescription drug monitoring.


Substance Abuse Services

Effective substance abuse treatment begins with a thorough evaluation.  At CMHC, adult and adolescent chemical dependency evaluations include:

  • Psychological evaluations.
  • Drug and alcohol use, abuse and dependence screening.
  • Toxicology tests and lab work, as needed.
  • Drug and alcohol abuse consultations with family members.

Levels of Care:

Following comprehensive evaluation, recommendation for a specific level of care will be discussed with the patient and family. 

CMHC provides outpatient individual substance abuse treatment programs. If a higher level of care is needed, appropriate referral will be made to other programs in the community. Psychiatric medication management is also available when needed. We realize that recovery involves more than just quitting drugs and/or alcohol. In addition to standardized treatment protocols, we will help you transform your life from the inside out through exercise, wellness education and nutrition programs that will help you properly nourish your body and mind. 

At CMHC, we layer individualized treatment plans with treatment methods that are supported by research and recognized by national organizations as effective for substance use disorders and/or co-occurring disorders.
