Persistent Depressive Disorder (Dysthymia) in Texas
Persistent depressive disorder is depressed mood on more days than not for at least two years, usually milder than a major episode but far longer. Because it feels like personality rather than illness, it is often untreated for a decade. It responds to treatment.

Understanding persistent depressive disorder
The defining feature is duration. Many people with persistent depressive disorder can describe function at work and at home, which is exactly why they and their doctors underestimate it: the impairment is chronic and low-grade rather than dramatic.
A common pattern is double depression, where a full major depressive episode lands on top of the chronic baseline. People often seek help only during that episode, get treated back to the chronic baseline, and are told they have recovered when they have not.
Treatment expectations differ from an acute episode. Chronic presentations generally need longer trials, sustained maintenance, and therapy that targets long-standing beliefs rather than a recent trigger.
Symptoms and when to seek an evaluation
- Low mood on more days than not for two years or longer
- Long-standing low self-esteem and pessimism
- Low energy and chronic fatigue as a baseline, not an episode
- Poor concentration or difficulty making decisions
- Appetite or sleep changes that have been present so long they seem normal
- A sense that this is simply your personality rather than an illness
Seek an evaluation when these symptoms have lasted for weeks, are getting worse, or are affecting your work, sleep, or relationships. If you are thinking about harming yourself, call or text 988 now.
What your first visit involves
- Lifetime mood timeline rather than a two-week symptom window
- Identifying superimposed major depressive episodes on the chronic baseline
- Screening for anxiety, ADHD, and substance use, which frequently accompany chronic low mood
- Function review across work, relationships, and self-care to size the real impairment
First appointments run longer than follow-ups so there is time to take a full history. You leave with a working diagnosis, a plan, and a follow-up date rather than a prescription and no explanation.
Therapy, psychiatry, and combined care
- Antidepressant treatment with a longer runway and clear maintenance plan
- Cognitive behavioural therapy aimed at entrenched beliefs, not a single recent trigger
- Combined medication and therapy, which has the strongest evidence in chronic presentations
- Explicit function goals so improvement is measured against life, not just a score
- Relapse-prevention planning before treatment is stepped down
Therapy and psychiatry are delivered in-house by clinicians licensed in Texas and share one chart, so a prescriber and a therapist working with you are looking at the same notes. Many people do best with both.
What we do not treat here
- Lyte does not provide inpatient or residential care
- Neuropsychological testing is not performed in-house
- Personality disorder treatment programmes are coordinated by referral rather than delivered at Lyte

Frequently asked questions
How is this different from major depression?
Major depression is defined by episodes lasting weeks; persistent depressive disorder is defined by a baseline lasting two years or more, often milder day to day. The two overlap when a major episode lands on top of the chronic baseline.
If I have felt this way since my teens, can it still be treated?
Yes. Long duration predicts a longer treatment runway, not a worse outcome. Many people describe the first real difference as noticing that a normal week no longer takes everything they have.
Is dysthymia the same thing?
Dysthymia is the older name. Current diagnostic criteria fold dysthymia and chronic major depression together under persistent depressive disorder.
Will I need medication forever?
Not necessarily, but chronic presentations relapse more often when treatment is stopped early. Any taper is planned deliberately with your prescriber rather than attempted at the first good month.
