Lab studies to diagnose or exclude medical conditions that may cause anxiety disorders include:
- Complete blood cell (CBC) count
- Chemistry profile
- Thyroid function tests
- Urinalysis
- Urine drug screen
Tests to rule out central nervous system (CNS) disorders that can cause anxiety include:
- Electroencephalography (EEG)
- Lumbar puncture
- Brain computed tomography (CT) scan
- Magnetic resonance imaging (MRI) of the brain
- Neurologic consultation
- Positron emission tomography (PET) scan
Tests to rule out heart conditions that can cause anxiety include:
- Electrocardiography (ECG)
- Treadmill ECG
Tests to rule out infectious causes of anxiety include:
- Rapid plasma reagent test
- Lumbar puncture (CNS infections)
- HIV testing
Other tests to rule out other physical causes of anxiety include:
- Arterial blood gas analysis
- Chest X-ray
What Is the Treatment for Anxiety Disorders?
Treatment for anxiety disorders usually consists of a combination of medication and/or psychotherapy. In the elderly, treatment must also consider a patient’s home environment, existing support systems or lack thereof, mobility, level of isolation, level of independence, ability to manage daily tasks, health history, and existing illnesses. There are professional care managers who can help assess all these elements and develop a treatment plan.
For the elderly, social day programs provide support and care that may help manage symptoms.
Types of therapy used to treat anxiety disorders include:
- Behavioral therapy and cognitive behavioral therapy (CBT)
- Computerized CBT (FearFighter)
- Psychodynamic therapy (or insight-oriented therapy) is rarely used on its own for phobias but may be used for phobic disorders that overlap personality disorders
- Interpersonal psychotherapy
- Relaxation therapy
- Supportive psychotherapy
- Mindfulness therapy
Medications that may be used to treat anxiety disorders include:
- Antidepressants
- Selective serotonin reuptake inhibitors (SSRIs)
- Serotonin and norepinephrine reuptake inhibitors (SNRIs)
- Atypical antidepressants
- Tricyclic antidepressants
- Monoamine oxidase inhibitors (MAOIs)
- Benzodiazepines, especially in emergency situations
- Anti-anxiety drugs
- Anticonvulsants
- Antihypertensive drugs
Other treatments used for anxiety disorders include:
- Cranial electrotherapy stimulator (CES) for treatment of anxiety, depression, and insomnia
Hospitalization may be indicated to treat anxiety disorders in severe cases such as:
- Severe functional impairment (cannot meet own daily needs)
- Suicide or homicide risk
- Deficits in social skills
